I Just Want to Be a Quiet Top Student

"The process of proving this question is very cumbersome, and there is no room to write on the blackboard." Shen Qi said.

"Shen Qi, your way of proving the law is very thoughtful, but the process is really cumbersome. No matter what, you have already proved a blackboard, so you have to finish it no matter what." Professor Lu said, he wanted to see Shen Qi complete the proof : "How many more blackboards do you need?"

Shen Qi thought for a while and said, "1.5 to two blackboards should be enough."

"Please continue with your proof." Professor Lu picked up the blackboard eraser and handed it to Shen Qi, and then asked the students in the audience: "The first part of the proof written by Shen Qi on the blackboard is based on the derivation of Fagnano's theorem. got it?"

Everyone shook their heads: "I don't understand."

Shen Qi explained: "When I finish writing all the proofs, everyone will understand."

Someone said: "The problem is that if you erase the previous proof and continue to write the latter, then we can't remember the previous one."

Professor Lu reminded: "Everyone can record the content on the blackboard in the notebook, instead of copying everything, just extract the core steps."

"Which steps are the core steps?"

"This, this, and this." Shen Qi tapped on different parts of the blackboard.

Zhou Yu'an was more flexible. He secretly took out his mobile phone and took pictures.

Then other students started to follow suit and took pictures.

Professor Lu turned to face the wall, closed his eyes and said, "I'll give you 10 seconds to extract the core steps on the blackboard."

Within 10 seconds, the students in the audience saved the first part of Shen Qi's proof on the blackboard on their mobile phones.

It is good to have a mobile phone, and the data transmission is completed in a few seconds.jpg

It takes several minutes to copy the mathematical symbols on a blackboard by hand, maybe more than that.

"Then I wiped it off." Shen Qi said to the students.

Students: "Wipe."

Professor Lu turned around, Shen Qi erased the first part of the proof on the blackboard, and continued his proof.

Next, Shen Qi processed the key equations through the Euler addition and multiplication theorems. This is a rather complicated process, and the amount of calculation is not very large. The difficulty lies in deriving the switching between logics.

The most difficult thing about counting points is not calculating, but being unable to calculate and not knowing how to calculate.

Obviously, the integral of dx/√[X] cannot be obtained with circular or logarithmic functions, and Shen Qi needs to find an algebraic full equation (22).

Shen Qi transformed the coefficient in the third integral radical and the lower limit of the integral through the sum of two integrals of the form ∫dx/√[R(x)], which cost half a blackboard.

When Shen Qi obtained the algebraic function of the common lower limit and the corresponding values ​​at the two upper limits, the blackboard was filled with writing again, so densely packed that not even one could be inserted.

Now that Shen Qi's proof is here, smart students in the audience have already grasped the core secret.

"So that's how it is, that's how it is."

"I should have thought of it, I should have thought of it."

"Shen Qi is awesome, very awesome."

"So it's...Legendre's three types of points!" Zhou Yu'an slapped his thigh fiercely. Who would have thought of this kind of proof, maybe even Professor Lu couldn't think of it in a short time.

"His logic is hard to understand, but it's very powerful." Ouye took the initiative to talk to Zhou Yu'an, through this proof question, she also learned something from Shen Qi.

Zhou Yu'an: "Hehe, it's the first time you've said such a long sentence to me, and let me digest it."

Jingle Bell.

At this time, the get out of class bell rang.

Shen Qi has filled two blackboards, but his proof has not been completed yet, and he is almost done.

"This..." Shen Qi lost his mind, "get out of class is over, let's come here today, Professor Lu?"

Professor Lu waved his hand: "No, get out of class will be dismissed after the certificate is completed, only a few steps away."

Then Professor Lu personally picked up the blackboard eraser and helped Shen Qi erase half of the blackboard: "It is equally regrettable to have no proof of completion and a novel without an ending."

"Okay." Shen Qi resorted to his big move, and with light-like hand speed, he completed the last few steps of proof on the blackboard.

The chalk characters are already somewhat scribbled, and ∫∞∈ looks like some kind of mysterious symbol, which seems to be linked to a void circle of another dimension.

The students from several colleges under the stage looked at it with dementia, even a little intoxicated.

More and more students gathered at the door of the classroom. They are not from several colleges. They come to class, and the next class is college English.

"who is he?"

"What is he doing?"

"Is he a student?"

"This... what are these things?"

"Ghost painting talisman?"

"math class?"

"Isn't this Shen Qi, from several colleges?"

"Sure enough, mathematics is similar to metaphysics. Should he summon pet beasts?"

The crowd of students at the door watched the excitement and talked a lot.

Finally, Shen Qi completed all the proofs, spending a total of 2.5 blackboards.

"The proof is complete." Shen Qi said to Professor Lu.

Professor Lu said: "If you, Shen Qi, start from the 24th equation and use the algebraic relationship between the integrals of double-needle lines, you can save half a blackboard, or even more."

"Professor Lu is right, I didn't think carefully enough." Shen Qi nodded, humbly accepting Professor Lu's suggestion.

"You are already great. Thinking of this kind of proof and completing the proof in a short time, it would be impossible for me thirty years ago." Professor Lu admired Shen Qi very much, and said to the students at the door: "Sorry, get out of class is over now."

"Is the proof method that the bald professor said is very serious?" The students at the door didn't understand it.

"The devil knows, we are liberal arts."

"What's the matter with Shen Qi, pretending to be X just a few days after school started?"

"Technically pretending to be X, I can't understand what he wrote at all, but I feel very powerful."

"It's too lethal to show off mathematics."

Professor Lu turned to the students in the School of Mathematics and said: "Time is limited, so I won't explain this proof question in detail today. I will talk about it in the next class, and the get out of class is over."

Then the students from several schools left, and the students from other schools entered for English class.

The Department of Mathematics and the Department of Science and Engineering Computing had no classes in the morning, and Shen Qi walked towards the building of the Mathematical Academy alone.

Entering the building of the Academy of Sciences and finding Sun Erxiong, Shen Qi raised some ideas: "Professor Sun, I don't have any acquaintances in Yanda. I only know you very well. I want to tell you something in my heart."

Sun Erxiong: "Say."

"Professor Sun, you asked me to go to the big class to re-learn the basic courses of mathematics majors such as fractions, advanced algebra, and solution. I did as you said. After a week of practice, I feel that Professor Lu, Professor Qu and You, Professor Sun, your lectures are very good, but... I am very embarrassed." Shen Qi was a little distressed.

"oh?"

"I have taught myself several times on counting points, advanced generation, and solution, but I can also understand that professors have to take care of most of the students. It is difficult for me to do it in a large class. If I don't play it, it will not reflect my level. , If you play too much, it’s easy to attract hatred. It’s okay for a week, a semester, a year, I’m afraid it won’t have a good impact, and it’s not conducive to the unity within our college.”
