The next day, in order to express his gratitude to Senior Chen who introduced this part-time job to him, Lu Zhou decided to treat her to dinner.
“…”
“…”
"Half of the points are in the second question. This kind of question is usually jointly examined with the vector question in the college entrance examination, so there is usually a second question..."
Han Mengqi looked impatient at first, but then her eyes gradually became serious as she stared at the paper.
Lu Zhou nodded silently and said nothing.
In the next few days, Lu Zhou's life was very regular. On Monday, Wednesday and Friday, he stayed up late and read books. Tuesday and Thursday were used to consolidate his studies and prepare for courses in other subjects such as information technology, electronic engineering, biology, chemistry, etc. In addition, he did not fall behind in mathematical modeling exercises.
"...You bully me." Han Mengqi threw away the pen, glared at Lu Zhou angrily and said, "I know I'm stupid."
Lu Zhou silently handed her a glass of water and asked, "What happened next?"
However, he was in a dilemma about whether to eat braised chicken or KFC.
I can't pretend I didn't hear this.
"… blackberries."
[In the rectangular coordinate system xoy, the left and right focus of ellipse C1: x square/a square + y square/b square = 1 (a>b>0) are F1 and F2 respectively. Among them, F2 is also the focus of parabola C2: y squared = 4x, point M is the intersection of C1 and C2 in the first quadrant, and |MF2|=5/3. Find the equation of C1.]
[Point N on the plane satisfies vector MN = vector MF1 + vector MF2, straight line l∥MN, and C1 intersects at two points A and B. If vector OA*OB=0, find the equation of straight line l.]
So, he asked Liu Rui, another living person in the dormitory, for his opinion.
Lu Zhou smiled, pulled out a paper from the pile of information next to him, pointed to the second to last big question, and continued: "And the most important thing is that this question is on this paper. Missed."
He doesn't really care about other people's private affairs. In a sense, he is a very selfish person.
As a result, after ten minutes, only the first step was solved.
"I'll add you as a friend! Give me your Q number... Ouch!"
"I'll add you as a friend! Give me your Q number... Ouch!"
Liu Rui, who was playing double row with netizens, was sent back to the spring by the opposite party. He was upset at the moment and did not listen carefully to Lu Zhou's question. He replied casually without looking back: "Spicy hotpot, cheap and good." Affordable!”
"You try to do it first. If you can't do it, I will teach you. It will take fifteen minutes. Let's start."
Lu Zhou:? ?
"You try to do it first. If you can't do it, I will teach you. It will take fifteen minutes. Let's start."
Then…
After waiting for about ten minutes, Lu Zhou looked at his watch, smiled and said, "During the college entrance examination, you were only allowed to think about a question for ten minutes at most. Looking at it now, the most you can get for this question is Three points.”
Lu Zhou couldn't help but sigh.
Is it that spicy
Lu Zhou really invited him.
Her little mouth moved slightly, Han Mengqi's brows furrowed as she stared intently at the draft paper, she nodded thoughtfully and said, "So that's how it is..."
Liu Rui, who was playing double row with netizens, was sent back to the spring by the opposite party. He was upset at the moment and did not listen carefully to Lu Zhou's question. He replied casually without looking back: "Spicy hotpot, cheap and good." Affordable!”
I don’t know if it was because he had a younger sister who was about the same age, but Lu Zhou didn’t feel impatient, nor did he ridicule her for asking for another “point question”. Instead, he patiently explained to her the ideas and process of solving the problem. .
"I'm just teaching you, and I never said you were stupid. On the contrary, I am very optimistic about your intelligence, so please don't belittle yourself." Lu Zhou picked up the pen she dropped and wrote the rest on the A4 paper. process, "The key to this kind of question is to determine the value of M, so the second step must be to set M (x1, y1), and based on |MF2|=5/3, and M2 on the parabola C2. Solve the conditions..."
Someone is talking bad about me behind my back
And it's like a rocket...
I don’t know if it was because he had a younger sister who was about the same age, but Lu Zhou didn’t feel impatient, nor did he ridicule her for asking for another “point question”. Instead, he patiently explained to her the ideas and process of solving the problem. .
It was even worse than the first question. This time Han Mengqi only wrote one solution, and not a single line of the rest was correct.
At the snack street at the school gate, at the entrance of Shancheng Malatang, Chen Yushan with a single ponytail sat opposite Lu Zhou, sticking out her tongue from the spicy food.
"Where's the remaining half?" Han Mengqi asked, tilting her head.
Han Mengqi looked impatient at first, but then her eyes gradually became serious as she stared at the paper.
Lu Zhou really invited him.
After finishing the Malatang, Lu Zhou took Senior Chen back to the dormitory building and then turned towards the library.
After waiting for about ten minutes, Lu Zhou looked at his watch, smiled and said, "During the college entrance examination, you were only allowed to think about a question for ten minutes at most. Looking at it now, the most you can get for this question is Three points.”
But more than a thousand yuan is not a lot of money. Counting the three thousand yuan he earned as a tutor yesterday, he now has more than seven thousand yuan in his card, which is definitely enough to pay the tuition.
Then…
Although she was almost in tears, Chen Yushan still held on and asked while eating, "How is it? Can my sister's math skills be saved?"
Following Han Mengqi's footsteps into the room, Lu Zhou was surprised to find that after a week without seeing her, she had tidied the room this time.
Maybe it was because of the last accident, or maybe it was some kind of agreement between mother and daughter. This time, Ms. Yang did not lock the door before going to work. She just told Lu Zhou to keep an eye on her daughter.
Jiupian SCI only spent so little money. It turns out that making missiles is not as good as frying poached eggs...
After writing this question, Lu Zhou made a gesture of invitation.
"According to the outline you gave me, I have already seen the analytic geometry of compulsory course two... and then what?"
Han Mengqi looked impatient at first, but then her eyes gradually became serious as she stared at the paper.
Lu Zhou silently handed her a glass of water and asked, "What happened next?"
It was even worse than the first question. This time Han Mengqi only wrote one solution, and not a single line of the rest was correct.
Is it that spicy
"Where's the remaining half?" Han Mengqi asked, tilting her head.
Lu Zhou wrote down the key to each step on paper and clarified his ideas for solving the problem.
Then…
Watching her mother out the door expressionlessly, Han Mengqi looked at Lu Zhou: "Then, let's get started."
Lu Zhou couldn't help but sigh.
Someone is talking bad about me behind my back
"No wonder my sister said you were mean..."
Lu Zhou threw a fish ball in his mouth with some confusion and said while chewing: "Is there any hope... maybe? Anyway, I will try my best."
"Well..." Han Mengqi gritted her teeth, looking unconvinced. However, problem solving is like this. Sometimes the more anxious you are, the harder it is to solve it.
The moment she saw the question, Han Mengqi was completely confused and looked at Lu Zhou helplessly.
[In the rectangular coordinate system xoy, the left and right focus of ellipse C1: x square/a square + y square/b square = 1 (a>b>0) are F1 and F2 respectively. Among them, F2 is also the focus of parabola C2: y squared = 4x, point M is the intersection of C1 and C2 in the first quadrant, and |MF2|=5/3. Find the equation of C1.]
After saying that, she turned back to her room.
I can't pretend I didn't hear this.
"Then it's up to you, my sister... In fact, her grades in science were very good in junior high school, but later... ah, it pissed me off."
He doesn't really care about other people's private affairs. In a sense, he is a very selfish person.
As he spoke, Lu Zhou continued to write at the end of the question.
"Well..." Han Mengqi gritted her teeth, looking unconvinced. However, problem solving is like this. Sometimes the more anxious you are, the harder it is to solve it.
"Then it's up to you, my sister... In fact, her grades in science were very good in junior high school, but later... ah, it pissed me off."
Another email was a reply from the journal "Modern Communications and Geographic Information Technology", stating that the manuscript fee has been paid to his bank card account. One article is 150 yuan, and the total is 1,350 yuan. Please pay attention to check.

Han Mengqi was so angry that her teeth itched, but there was nothing she could do about him, so she could only snort.
"… blackberries."
After writing this question, Lu Zhou made a gesture of invitation.
Looking at the steps on the draft paper, Han Mengqi's eyes widened and she whispered: "It's amazing..."
Then…
Gritting her teeth, she picked up the pen and thought about it for a long time on the draft paper.
After drinking the water in one gulp, Chen Yushan stuck out her tongue cutely, took a breath and continued: "Later... my aunt and uncle had some relationship problems, and the two were fighting for the custody of Meng Qi. I don't know the specific situation. , in short, Meng Qi is staying with my aunt for the time being."
"Where's the remaining half?" Han Mengqi asked, tilting her head.
But with the help of the system, this process is accelerated.

After finishing the Malatang, Lu Zhou took Senior Chen back to the dormitory building and then turned towards the library.
Sometimes he really feels that if he can really maintain such good study habits, even without systematic help, it will be a matter of time before he becomes a top student.
Lu Zhou:? ?
"I'll add you as a friend! Give me your Q number... Ouch!"

On his way to the library, he received two pieces of mail.
"Our second goal is to find the half-focal length of ellipse C1. After solving this step, the remaining problems become problems of understanding the system of equations."

At the snack street at the school gate, at the entrance of Shancheng Malatang, Chen Yushan with a single ponytail sat opposite Lu Zhou, sticking out her tongue from the spicy food.
An email was from Teacher Liu, giving feedback on the data modeling assignment.
"I'm just teaching you, and I never said you were stupid. On the contrary, I am very optimistic about your intelligence, so please don't belittle yourself." Lu Zhou picked up the pen she dropped and wrote the rest on the A4 paper. process, "The key to this kind of question is to determine the value of M, so the second step must be to set M (x1, y1), and based on |MF2|=5/3, and M2 on the parabola C2.

However, Lu Zhou didn't look at her. Instead, he sat beside the bed and picked up the exercise book next to him, looking for the next example question.

Han Mengqi's eyebrows twitched slightly. She just said something big, but she didn't expect Lu Zhou to test her on the spot.
An email was from Teacher Liu, giving feedback on the data modeling assignment.
Lu Zhou silently handed her a glass of water and asked, "What happened next?"
"Then?" Lu Zhou raised his eyebrows and asked with a smile, "First tell me what you don't understand?"
Lu Zhou reached out and tapped her on the forehead. Looking at her covering her forehead, he said angrily, "You're still playing games. I'll wait until you get 100 points in the math test this month!"
He doesn't really care about other people's private affairs. In a sense, he is a very selfish person.

The next day, in order to express his gratitude to Senior Chen who introduced this part-time job to him, Lu Zhou decided to treat her to dinner.
Originally, he planned to put it off and make up for it all at once before graduation, but now it seems that there is no need for it.
"Then it's up to you, my sister... In fact, her grades in science were very good in junior high school, but later... ah, it pissed me off."

On Saturday, Lu Zhou went to Ms. Yang's home as usual to tutor Han Mengqi in mathematics.
However, he was in a dilemma about whether to eat braised chicken or KFC.
But with the help of the system, this process is accelerated.

"Half of the points are in the second question. This kind of question is usually jointly examined with the vector question in the college entrance examination, so there is usually a second question..."
Sometimes he really feels that if he can really maintain such good study habits, even without systematic help, it will be a matter of time before he becomes a top student.
Lu Zhou:? ?
As a result, after ten minutes, only the first step was solved.
But more than a thousand yuan is not a lot of money. Counting the three thousand yuan he earned as a tutor yesterday, he now has more than seven thousand yuan in his card, which is definitely enough to pay the tuition.
So, he asked Liu Rui, another living person in the dormitory, for his opinion.
Finally, a glimmer of realization dawned on her face.
Right now-
"There's nothing I don't understand. It feels pretty simple." Han Mengqi raised her little head and said impatiently, "Then what?"
Han Mengqi was so angry that her teeth itched, but there was nothing she could do about him, so she could only snort.
"Well..." Han Mengqi gritted her teeth, looking unconvinced. However, problem solving is like this. Sometimes the more anxious you are, the harder it is to solve it.
Although she was almost in tears, Chen Yushan still held on and asked while eating, "How is it? Can my sister's math skills be saved?"
Right now-
Lu Zhou silently handed her a glass of water and asked, "What happened next?"
He doesn't really care about other people's private affairs. In a sense, he is a very selfish person.
It was even worse than the first question. This time Han Mengqi only wrote one solution, and not a single line of the rest was correct.
I can't pretend I didn't hear this.
Lu Zhou:? ?
"My learning process is to constantly summarize and learn from my mistakes. I hope you can find out the questions you don't know at ordinary times, preferably by copying them in a notebook. Then I will explain them to you every week," Lu Zhou said The question was returned to Han Mengqi, and he said casually, "The wrong questions are necessary for learning mathematics, and even all science subjects. If you want to learn science well, you must prepare. Just like the ADC takes Dolan with him when he goes out, and the support needs to bring eyes, these are all basic operate."
Lu Zhou really invited him.
[Obtained from C2: y squared = 4x, F2 (1, 0).]
As he spoke, Lu Zhou continued to write at the end of the question.
"Where's the remaining half?" Han Mengqi asked, tilting her head.
So, he asked Liu Rui, another living person in the dormitory, for his opinion.
I can't pretend I didn't hear this.
"I'm just teaching you, and I never said you were stupid. On the contrary, I am very optimistic about your intelligence, so please don't belittle yourself." Lu Zhou picked up the pen she dropped and wrote the rest on the A4 paper. process, "The key to this kind of question is to determine the value of M, so the second step must be to set M (x1, y1), and based on |MF2|=5/3, and M2 on the parabola C2. Solve the conditions..."
After waiting for about ten minutes, Lu Zhou looked at his watch, smiled and said, "During the college entrance examination, you were only allowed to think about a question for ten minutes at most. Looking at it now, the most you can get for this question is Three points.”
Someone is talking bad about me behind my back
Lu Zhou wrote down the key to each step on paper and clarified his ideas for solving the problem.
"Well..." Han Mengqi gritted her teeth, looking unconvinced. However, problem solving is like this. Sometimes the more anxious you are, the harder it is to solve it.
Originally, he planned to put it off and make up for it all at once before graduation, but now it seems that there is no need for it.
As a result, after ten minutes, only the first step was solved.
Lu Zhou smiled, pulled out a paper from the pile of information next to him, pointed to the second to last big question, and continued: "And the most important thing is that this question is on this paper. Missed."
He doesn't really care about other people's private affairs. In a sense, he is a very selfish person.
Han Mengqi's eyebrows twitched slightly. She just said something big, but she didn't expect Lu Zhou to test her on the spot.
Is it that spicy
Lu Zhou reached out and tapped her on the forehead. Looking at her covering her forehead, he said angrily, "You're still playing games. I'll wait until you get 100 points in the math test this month!"
"...You bully me." Han Mengqi threw away the pen, glared at Lu Zhou angrily and said, "I know I'm stupid."
"I'm just teaching you, and I never said you were stupid. On the contrary, I am very optimistic about your intelligence, so please don't belittle yourself."

"Well..." Han Mengqi gritted her teeth, looking unconvinced. However, problem solving is like this. Sometimes the more anxious you are, the harder it is to solve it.
"Our second goal is to find the half-focal length of ellipse C1. After solving this step, the remaining problems become problems of understanding the system of equations."

Han Mengqi looked impatient at first, but then her eyes gradually became serious as she stared at the paper.

But more than a thousand yuan is not a lot of money. Counting the three thousand yuan he earned as a tutor yesterday, he now has more than seven thousand yuan in his card, which is definitely enough to pay the tuition.
On Saturday, Lu Zhou went to Ms. Yang's home as usual to tutor Han Mengqi in mathematics.
Lu Zhou nodded silently and said nothing.
He doesn't really care about other people's private affairs. In a sense, he is a very selfish person.
Although she was almost in tears, Chen Yushan still held on and asked while eating, "How is it? Can my sister's math skills be saved?"
As a result, after ten minutes, only the first step was solved.
Lu Zhou wrote down the key to each step on paper and clarified his ideas for solving the problem.
"You try to do it first. If you can't do it, I will teach you. It will take fifteen minutes. Let's start."
After finishing the Malatang, Lu Zhou took Senior Chen back to the dormitory building and then turned towards the library.
Han Mengqi's eyes lit up and she immediately became interested and interrupted: "You want to play with me too? Which district are you in? My wet nurse is a thief!"
Han Mengqi looked impatient at first, but then her eyes gradually became serious as she stared at the paper.
"Half of the points are in the second question. This kind of question is usually jointly examined with the vector question in the college entrance examination, so there is usually a second question..."
In the next few days, Lu Zhou's life was very regular. On Monday, Wednesday and Friday, he stayed up late and read books. Tuesday and Thursday were used to consolidate his studies and prepare for courses in other subjects such as information technology, electronic engineering, biology, chemistry, etc. In addition, he did not fall behind in mathematical modeling exercises.
"Your teacher must have told it, but you haven't heard it at all."
Gritting her teeth, she picked up the pen and thought about it for a long time on the draft paper.
"Half of the points are in the second question. This kind of question is usually jointly examined with the vector question in the college entrance examination, so there is usually a second question..."
The moment she saw the question, Han Mengqi was completely confused and looked at Lu Zhou helplessly.
Finally, a glimmer of realization dawned on her face.
I don’t know if it was because he had a younger sister who was about the same age, but Lu Zhou didn’t feel impatient, nor did he ridicule her for asking for another “point question”. Instead, he patiently explained to her the ideas and process of solving the problem. .
Gritting her teeth, she picked up the pen and thought about it for a long time on the draft paper.
Gritting her teeth, she picked up the pen and thought about it for a long time on the draft paper.
At the snack street at the school gate, at the entrance of Shancheng Malatang, Chen Yushan with a single ponytail sat opposite Lu Zhou, sticking out her tongue from the spicy food.
Her little mouth moved slightly, Han Mengqi's brows furrowed as she stared intently at the draft paper, she nodded thoughtfully and said, "So that's how it is..."
I can't pretend I didn't hear this.
Gritting her teeth, she picked up the pen and thought about it for a long time on the draft paper.
"Your teacher must have told it, but you haven't heard it at all."
[Obtained from C2: y squared = 4x, F2 (1, 0).]
The next day, in order to express his gratitude to Senior Chen who introduced this part-time job to him, Lu Zhou decided to treat her to dinner.
However, Lu Zhou didn't look at her. Instead, he sat beside the bed and picked up the exercise book next to him, looking for the next example question.

Following Han Mengqi's footsteps into the room, Lu Zhou was surprised to find that after a week without seeing her, she had tidied the room this time.
As he spoke, Lu Zhou continued to write at the end of the question.
"Our teacher... didn't explain it in detail as you did." Han Mengqi said reluctantly.
Lu Zhou silently handed her a glass of water and asked, "What happened next?"
"There's nothing I don't understand. It feels pretty simple." Han Mengqi raised her little head and said impatiently, "Then what?"
Without any unnecessary communication, Han Mengqi spread the book on the table, turned to the dog-eared page, and looked at Lu Zhou.
Someone is talking bad about me behind my back
Lu Zhou silently handed her a glass of water and asked, "What happened next?"
Another email was a reply from the journal "Modern Communications and Geographic Information Technology", stating that the manuscript fee has been paid to his bank card account. One article is 150 yuan, and the total is 1,350 yuan. Please pay attention to check.
Lu Zhou was amused: "You might as well tell your math teacher this, and let's see if we can piss him off to death."
Maybe it was because of the last accident, or maybe it was some kind of agreement between mother and daughter. This time, Ms. Yang did not lock the door before going to work. She just told Lu Zhou to keep an eye on her daughter.
"Well..." Han Mengqi gritted her teeth, looking unconvinced. However, problem solving is like this. Sometimes the more anxious you are, the harder it is to solve it.

Lu Zhou nodded silently and said nothing.
Han Mengqi was so angry that her teeth itched, but there was nothing she could do about him, so she could only snort.

Watching her mother out the door expressionlessly, Han Mengqi looked at Lu Zhou: "Then, let's get started."

"Then?" Lu Zhou raised his eyebrows and asked with a smile, "First tell me what you don't understand?"
Lu Zhou wrote down the key to each step on paper and clarified his ideas for solving the problem.
"No wonder my sister said you were mean..."
Her little mouth moved slightly, Han Mengqi's brows furrowed as she stared intently at the draft paper, she nodded thoughtfully and said, "So that's how it is..."
Lu Zhou smiled, pulled out a paper from the pile of information next to him, pointed to the second to last big question, and continued: "And the most important thing is that this question is on this paper. Missed."
"Where's the remaining half?" Han Mengqi asked, tilting her head.
"… blackberries."
Lu Zhou:? ?
Han Mengqi looked impatient at first, but then her eyes gradually became serious as she stared at the paper.
Jiupian SCI only spent so little money. It turns out that making missiles is not as good as frying poached eggs...
After saying that, she turned back to her room.
Then…
"No wonder my sister said you were mean..."
"Then I will give you a test." Lu Zhou took a piece of A4 paper from the side and wrote on it with a pen.
Although she was almost in tears, Chen Yushan still held on and asked while eating, "How is it? Can my sister's math skills be saved?"
"There's nothing I don't understand. It feels pretty simple." Han Mengqi raised her little head and said impatiently, "Then what?"
Someone is talking bad about me behind my back
Lu Zhou really invited him.
An email was from Teacher Liu, giving feedback on the data modeling assignment.
"Then?" Lu Zhou raised his eyebrows and asked with a smile, "First tell me what you don't understand?"
I can't pretend I didn't hear this.
Watching her mother out the door expressionlessly, Han Mengqi looked at Lu Zhou: "Then, let's get started."
Lu Zhou coughed and ended the topic. He picked up the pen and said, "This question is a typical intersection point problem of finding elliptic equations. I believe you can get at least half of the points next time you encounter this type of question." .”

Han Mengqi was so angry that her teeth itched, but there was nothing she could do about him, so she could only snort.
Lu Zhou threw a fish ball in his mouth with some confusion and said while chewing: "Is there any hope... maybe? Anyway, I will try my best."
Following Han Mengqi's footsteps into the room, Lu Zhou was surprised to find that after a week without seeing her, she had tidied the room this time.
Gritting her teeth, she picked up the pen and thought about it for a long time on the draft paper.
"Then it's up to you, my sister... In fact, her grades in science were very good in junior high school, but later... ah, it pissed me off."
Lu Zhou couldn't help but sigh.
Sometimes he really feels that if he can really maintain such good study habits, even without systematic help, it will be a matter of time before he becomes a top student.
"Where's the remaining half?" Han Mengqi asked, tilting her head.
[In the rectangular coordinate system xoy, the left and right focus of ellipse C1: x square/a square + y square/b square = 1 (a>b>0) are F1 and F2 respectively. Among them, F2 is also the focus of parabola C2: y squared = 4x, point M is the intersection of C1 and C2 in the first quadrant, and |MF2|=5/3. Find the equation of C1.]
However, Lu Zhou didn't look at her. Instead, he sat beside the bed and picked up the exercise book next to him, looking for the next example question.

"I'll add you as a friend! Give me your Q number... Ouch!"
Right now-
"There's nothing I don't understand. It feels pretty simple." Han Mengqi raised her little head and said impatiently, "Then what?"
[Point N on the plane satisfies vector MN = vector MF1 + vector MF2, straight line l∥MN, and C1 intersects at two points A and B. If vector OA*OB=0, find the equation of straight line l.]
"Where's the remaining half?" Han Mengqi asked, tilting her head.
Lu Zhou:? ?

Looking at the steps on the draft paper, Han Mengqi's eyes widened and she whispered: "It's amazing..."
Lu Zhou wrote down the key to each step on paper and clarified his ideas for solving the problem.
Han Mengqi looked impatient at first, but then her eyes gradually became serious as she stared at the paper.

However, he was in a dilemma about whether to eat braised chicken or KFC.

After drinking the water in one gulp, Chen Yushan stuck out her tongue cutely, took a breath and continued: "Later... my aunt and uncle had some relationship problems, and the two were fighting for the custody of Meng Qi. I don't know the specific situation. , in short, Meng Qi is staying with my aunt for the time being."
