"Mathematics is a tool. If you want to use the tool, you can't just learn the tool." Shen Hui was not at all stage fright. When she saw Niu Kaihuai leaving, she did not erase the questions written by Niu Kaihuai, but started to explain directly.
"High-order derivatives can be combined with gravity exploration. The gravity anomaly value of a specified area can be obtained through a gravimeter, and the key parameters such as the occurrence, shape, and spatial position of the underground geological body can be obtained through gravity anomalies.
However, the obtained gravity anomaly is often a superimposed anomaly of underground geological bodies and will be interfered by various factors. This requires the use of high-order derivatives to reasonably process the obtained gravity anomaly. "
"The high-order derivative is essentially a filter that can highlight the gravity anomalies of shallow and small geological bodies and suppress the influence of regional geological factors with deep burial depths. It can also separate the gravity anomalies caused by several geological bodies with similar burial depths and close to each other..."
Niu Kaihuai originally wanted to watch the show and see how capable Shen Hui was to be so arrogant.
In his heart, Shen Hui is just an ordinary genius. It is normal for geniuses to be a little arrogant, but there are so many students in the class, who is not a genius? The arrogance that Shen Hui can use in other places does not mean that she can also use it in this class... Fuck, she seems to be really able to be arrogant!
"First, based on the basic theory of gravity field, we derive the calculation formulas for gravity anomalies and partial derivatives of various orders..."
"Convert the formula for calculating higher-order derivatives..."
“Two types of models can be designed here: two-dimensional and three-dimensional…”
"Next, two high-order derivative methods are used to calculate the vertical second-order derivative to demonstrate that the intersection of two vertical second-order derivative curves of different radii can be used to determine the model's boundary and its approximate projection position on the ground..."
“This is the practical application of higher-order derivatives.”
Shen Hui finished teaching.
During the two classes, Shen Hui did not stop during the break, and no students walked around or left the class.
I taught like this for nearly two classes in a row.
No, to be precise, Shen Hui gave two lectures herself.
Shen Hui said these things not to teach anyone, but to prove that she was stronger than Niu Kaihuai. As long as she was strong enough, she would not need Niu Kaihuai's guidance, nor would she need to accept the constraints from a teacher.
Shen Hui was about to step down from the podium when someone suddenly asked, "Teacher Shen! I have a question! It's not about math, it's about the Frotran program."
Shen Hui felt a little strange when someone called her teacher for the first time. She did not answer and walked down the platform directly. "I am not your teacher, and I don't want to answer your questions."
After saying that, Shen Hui walked to her seat where Niu Kaihuai was sitting. Shen Hui said bluntly, "Please move aside. Your students are asking you questions."
Niu Kaihuai didn't say anything this time. He just stood up and walked to the podium and smiled and said, "I know the Frotran program. Let your teacher Niu explain it to you."
After Niu Kaihuai took over the conversation, the class seemed to return to normal.
Only Niu Kaihuai knows how much pain he is in now.
Wow, Shen Yichen, you really threw a bomb at me. This is no longer the genius level of a kid. This is the level of someone who can be my colleague!
