"Math is a tool. To use a tool, you can't just study the tool itself," Shen Hui was not the least bit intimidated. Seeing Niu Kaihuai write down questions, she did not erase what Niu Kaihuai had written but instead started lecturing directly.
"Higher-order derivatives can be combined with gravity exploration. Gravity meters can obtain gravity anomaly values for specified areas. Gravity anomalies can reveal key parameters about the occurrence, shape, and spatial location of underground geological bodies.
However, the obtained gravity anomaly is often a superimposed anomaly of the underground geological body, which can be interfered with by many factors. This requires reasonable processing of the obtained gravity anomaly using higher-order derivatives.
Higher-order derivatives are essentially a filter that can highlight the gravity anomalies of shallow and small geological bodies and suppress the effects of regional, deeper buried geological factors. It can also separate gravity anomalies caused by several geological bodies with slightly different burial depths that are close to each other..."
Niu Kaihuai originally still had the mentality of watching a good show, wanting to see what skills Shen Hui had to dare be so arrogant.
In his mind, Shen Hui was just an ordinary genius. It is normal for geniuses to have some arrogance, but every student in the class is a genius. The arrogance that Shen Hui can get away with in other places does not mean she can also be arrogant in this class... Damn, she really can be arrogant!
"First, based on the basic theory of the gravity field, derive the calculation formulas for gravity anomalies and partial derivatives of each order..."
"Convert the calculation formulas for higher order derivatives..."
"Here we can design two types of 2D and 3D models..."
"Next, use two different higher order derivative methods to calculate their vertical second order derivatives, to prove that the boundaries of the model and the approximate projection position on the ground can be determined using the intersection of two vertical second order derivative curves with different radii..."
"This is the actual application of higher order derivatives."
Shen Hui finished teaching.
Two periods, during the break between classes, Shen Hui did not stop, and no students in the class moved or left.
She just taught for nearly two consecutive periods.
No, to be precise, Shen Hui taught two classes by herself.
What Shen Hui said was not to teach anyone, but to prove that she was stronger than Niu Kaihuai. As long as she was strong enough, she didn't need Niu Kaihuai's guidance or need to accept restraints from the teacher.
After Shen Hui finished speaking, she was about to step down from the podium when suddenly someone below asked a question, "Teacher Shen! I have a question! It's not about math, it's about the Frotran program."
Shen Hui felt a little strange being called teacher for the first time. She did not answer and went directly down from the podium, "I am not your teacher and I don't want to answer your questions."
After speaking, Shen Hui went to her seat, where Niu Kaihuai was still sitting. Shen Hui unceremoniously said, "Please make way, your students are asking you questions."
This time, Niu Kaihuai didn't say anything. He stood up directly and came to the podium with a smile to pick up the conversation, "I know about the Frotran program, so let your Niu teacher come and explain it to you."
After Niu Kaihuai took over, the class seemed to have returned to its original state.
Only Niu Kaihuai knew how painful he was now.
Wow, Shen Yichen, you kid really threw a bomb at me. This is no longer a genius level for a child, right? This is already at the level where she can be my colleague!
Of course, Niu Kaihuai was a very capable teacher. Even if he scolded Shen Yichen in his heart, he still behaved very naturally on the surface and could still teach.
Niu Kaihuai was also a genius, a multi-tasking genius!
After sitting down again, Shen Hui looked at Shen Yue. She intuitively felt that Shen Yue might say something to her at this time, but in fact she didn't. Shen Yue was listening to Niu Kaihuai's lecture, just like she had listened carefully to her lecture on higher-order derivatives just now.
Shen Hui opened her mouth to try to talk to Shen Yue, but swallowed back the words that came to her mouth, just looking out the window alone.
She didn't need teachers in her school life.
...
Niu Kaihuai didn't teach for long before the end of class bell rang.
Usually even if the bell rang, as long as there were still students asking Niu Kaihuai questions, he would stay behind to help answer students' questions. But this time, he ran away very quickly, somewhat akin to fleeing.
Of course, this fleeing was in the eyes of the classmates. Niu Kaihuai was actually going to report to other teachers.
[Special Class Teacher Group]: Damn, this new student Shen Hui is really going to be the death of me. I don't know which national team she is from. Everyone be careful to dodge!!!
Shen Hui still didn't know that she was about to become a figure that made teachers terrified. She was secretly looking at Shen Yue.
After class, Shen Yue still didn't talk to her or anyone else come to find her or Shen Yue.
Shen Hui looked at the classmates in the class from the corner of her eye. Those people stayed far away from her, completely unlike their enthusiastic greetings to Shen Yue and herself when they first entered the classroom this morning.
Shen Yue saw Shen Hui's puzzlement and finally tilted her head and leaned on Shen Hui's shoulder and said softly, "Huihui, you did something wrong."
Shen Hui frowned when she heard Shen Yue's first sentence after class was criticism of herself. She didn't speak or push Shen Yue away, just silently letting her lean there.
It seemed that Shen Yue didn't expect Shen Hui to answer either. After leaning for a while, she got up.
She stood up and straightened her skirt, then stood next to Shen Hui, "Teacher Niu is a good teacher. Actually there were many times just now when he could have taught you a lesson, but he didn't. What he thought of first was preserving your self-esteem, your arrogance. As your sister, I'm going to thank him for giving you a chance, and apologize."
