Qing Xiaoyu explained in great detail, and Zou Xuerong quickly learned what she meant and thanked her in a low voice.
But Shen Yue and Jiang Shiwen still opened their confused yet clear eyes, and the four words "I don't understand" were clearly written on their faces.
Shen Yue was simply too lazy to use her brain and just wanted to enjoy the feeling of being noticed when Qing Xiaoyu was explaining the questions to her, while Jiang Shiwen tried his best to understand but still couldn't understand.
Qing Xiaoyu looked at the time and started to shoo people away, "The afternoon class is about to start, why aren't you leaving yet?"
When Zou Xuerong saw the time, she immediately panicked. Today was her first day of school and she couldn't be late. Fortunately, her classroom was right next door.
"Then I'll go first. Yueyue, I'll come see you after school..." After saying that, Zou Xuerong said softly to Qing Xiaoyu, "Thank you too."
Qing Xiaoyu replied politely, "You're welcome."
Jiang Shiwen was very crazy, but he followed Zou Xuerong.
Normally his grades in class are not too bad, just below average. The teachers never say anything bad about him, and he feels good about himself.
But today, he was being taught how to do a problem by a kid younger than him, and he still didn’t understand. This was really unbearable!
He can choose not to learn, but he cannot learn and not understand!
Jiang Shiwen secretly made up his mind to study hard from today on, so that at least he would be able to understand it next time.
The first class in the afternoon was math class. As soon as Niu Kaihuai walked into the classroom, he saw Shen Yue who was sober. He raised his eyebrows in surprise.
Niu Kaihuai believed that he was never a person who would wrong himself. He had to know what he wanted to know, so he asked Shen Yue directly, "Why don't you sleep?"
Shen Yue:
Seeing that Shen Yue didn't answer, Niu Kaihuai thought she didn't hear clearly, so he asked again, "Why didn't you sleep today?"
Shen Yue was sure that this was a question for her, so she replied, "To get a good night's sleep."
After hearing this answer, Niu Kaihuai actually felt it was very reasonable, but not so reasonable.
Seeing Shen Yue's peaceful face, Niu Kaihuai wrote a question on the blackboard and said to Shen Yue, "Shen Yue, come up and solve this question before class. If you can't solve it, you will have to stand during the class."
Today I, Lao Niu, want to see whether you are truly sober or just pretending to be sober.
The question on the blackboard is very concise. Prove:
tan1＞3/2.
This is a very routine proof question, but it is undoubtedly beyond the syllabus for ordinary first-year junior high school students who have only learned some basic formulas.
Ye Yin only took a glance and suspected that Shen Yue had offended Lao Niutou, otherwise why would he ask her such a question.
If you use the conventional method to solve this problem, you need to first draw a tangent line of y = tanx at x = π/3.
Then use f(x) to assume the derivative and prove that it is monotonically decreasing within the domain of definition, so as to prove that tan1＞3/2.
There are only five minutes left before class starts. If you have not fully mastered the knowledge needed to solve this problem and are very familiar with this type of question, it will be impossible to solve it within five minutes.
Ye Yin couldn't help but worry about Shen Yue.
However, if Shen Yue doesn't know how to solve this problem later, he can take the opportunity to talk to Shen Yue while explaining the problem.
No, no, no, no, no, his idea is wrong! How could he have such a vicious idea! He actually cursed his classmates for not being able to solve the problem!
