From Almighty Scholar to Chief Scientist

Chapter 6 System Rewards: Brain Development
Since this exam is a math exam, Ding Ping, as a math teacher, might as well come and see how the students answered the questions.

It took him about [-] minutes just now to read all the questions. If you want to evaluate the difficulty, it is probably a medium difficulty for the third year of high school, not particularly difficult. It can be regarded as reducing the pressure these students face when they start school.

However, I just don't know if these top students in the first examination room will make some mistakes that shouldn't be made when they are doing the questions.

Sometimes, some mistakes will make him feel ridiculous, which can be regarded as a kind of fun during the invigilation.

Arriving at the first row, that is, the row of the top six, Ding Ping looked at the No.1 student in the last exam grade with his hands behind his back.

This is a girl. As No.1, she is naturally not too weak in mathematics, but she is not considered a master of mathematics like Lin Xiao and Jiang Jie. Her strengths are mainly English and Chinese.

Ding Ping looked at it for a while, and determined that the girl made a wrong choice and a fill-in-the-blank, both of which were the last and the most difficult, but in this way, she could only get 140 points at most. If there are some problems again, you can only get more than 130.

With a calm expression on his face, Ding Ping stopped paying attention to this girl.

Looking at the back row, he found Jiang Jie sitting in the fourth row.

He naturally knew Jiang Jie, after all, he was in his competition training class.

Jiang Jie also performed well in the training class. Although he is a bit arrogant, his strength is still good, at least a little stronger than those students in the second year of high school.

So Ding Ping walked behind Jiang Jie and looked at his situation.

"Well, this Jiang Jie's writing is pretty good, and the speed is pretty fast. It's only been 10 minutes, and I have written the second question of the ellipse question. There is also a function question and an elective question. The function question is relatively simple. , it is estimated that it will not be difficult for him."

"The multiple-choice questions and the fill-in-the-blank questions should all be correct, as well as the first few major questions. The writing is good."

Looking at Jiang Jie's situation through the answer sheet, he nodded with satisfaction. Jiang Jie said before that he wanted to get the provincial first grade. Although Ding Ping had no hope for this, after all, those colleges and universities in Xijing invested far more in competition classes than theirs. The remote city is much bigger. If you want to win the top few places in the competition, you don't have enough talent and energy to invest, so you can't compare to Xijing.

Of course, the probability of Jiang Jie getting the second province is quite high, and Ding Ping still believes it.

Then he stopped looking, and went on looking at other people.

In this way, he walked around and walked to the last row.

At this time, he was too lazy to look at one person, but when he walked quickly to the second row, his corner of the eye glanced at the draft paper of the student in the fifth row, which was Lin Xiao.

"Huh? What is this student writing?"

He narrowed his eyes, suspicious.

The neat column formulas on the draft paper, as well as some complex functional formulas, all attracted his attention.

When he saw the first line of words, he was stunned.

"Taylor's Mean Value Theorem? Proof?"

He couldn't help being at a loss. Is there such a question on the test paper?

But he quickly realized that maybe the student had finished writing the test paper, and then tried to prove Taylor's mean value theorem?

So he quickly glanced at Lin Xiao's answer sheet, showing such an expression.

I saw the back of the answer sheet, which was filled with various formulas, including conic sections and functions, as well as the final elective questions.

He couldn't believe it, it had only been more than 80 minutes, and the student had already finished all the work?

He couldn't help but looked at Lin Xiao's problem-solving process again. The ellipse problem was the most difficult one in this paper. After seeing Lin Xiao's problem-solving method, he was even more surprised.

"This method... is ok. I actually thought of converting it into a polar coordinate equation, and then constructing a polar coordinate equation of a circle with the focal length as its diameter, which directly simplifies the whole problem."

He couldn't help admiring in his heart, this method is very brilliant, and then he looked at other questions, and Lin Xiao's methods all made him praise.

He just didn't know how the previous questions were written, and he couldn't see the front page of the answer sheet.

At this time, he also confirmed that the student probably wrote this proof of Taylor's mean value theorem because he was bored after finishing the questions.

So he looked at Lin Xiao's proof process again, and he felt sincere appreciation in his heart.

"This student has learned Taylor's mean value theorem by himself, so he probably has studied advanced mathematics."

"This is proved by mathematical induction, and the thinking is correct. There is no problem. It seems that the student's knowledge has reached the level of comprehension."

And this is obviously not an easy task for a high school student.

Lin Xiao's proof is not shocking, and many people have already done it.

But those who have done it are basically undergraduates, but now it is only done by a senior high school student.

And you must know that as long as this proof is completed, it is enough for some mathematics undergraduates to use it as an undergraduate graduation thesis.

"Let me see, what is the name of this student, um, the first class of science is called Lin Xiao, hey... I remember that there is a student named Lin Xiao in the first class of science who can also participate in the league, but he didn't come to participate in the training. It should be this student, right?"

Ding Ping couldn't help wondering, this student is so good at mathematics, why didn't he take part in the training?
Even if it is to learn about the types of league questions, it will be very helpful for the future competitions, right?

And this Lin Xiao's talent should be very good. It took about 10 minutes for him to write this proof of Taylor's mean value theorem.

Doesn't this mean that he just spent more than 70 or even more than 60 minutes to write all the exam questions?

That Jiang Jie just now was not as powerful as him.

Thinking so in his heart, at this time he also saw Lin Xiao raised his head, and saw that he wrote the last two words on the draft paper with a sense of ritual: Zhengbi.

It appears that the proof is done.

Ding Ping shook his head and returned to the podium, but he had already written down Lin Xiao's name.

And Lin Xiao had just recovered from the state of immersion at this time, so he never noticed that the invigilator was right behind him. Even though Ding Ping passed by, he didn't care, just regarded it as the teacher passing by normally.

He threw the pen away, picked up the draft paper, and blew on it, with a satisfied expression on his face.

Well, it's basically done.

It's very simple.

He is indeed a genius!

At this time, the voice of the system suddenly sounded: "The host has completed the proof of Taylor's median value theorem after independent thinking. Considering the host's ability, rewards: +2 mathematical experience, +1 truth point, because it is the first time to achieve Achievement, in order to help the host to better explore the truth, reward the host's brain development by 0.5%."

The next moment, Lin Xiao suddenly felt his head sink, and then a sense of dizziness flooded his mind.
