Some college students will find it strange that they are all classmates in the same class, why don't I understand, but some people are full of praise and say that they have benefited a lot?

Why can't I understand the same textbook, but some people have ten lines at a glance?

What's even more infuriating is that we all have 24 hours a day, why do some people not only finish the textbook, but also learn a lot of knowledge outside the textbook, where do they get so much time?

Why is that?

It's not scientific.

"Some students may think that my lectures are too jumpy, so why do I suddenly jump to the second type of symmetry of the surface of the curvature?" Professor Lu said while wiping the blackboard, "Of course I have my own teaching ideas, and you will be able to understand them in the future." ”

"Not really. Some students in the audience muttered quietly.

"After only two classes, I wanted to give up on treatment. Some students expressed pessimism.

Mathematics students are better, most of them can follow Professor Lu's train of thought.

Most students in the Department of Science and Engineering Computing are in a state of confusion for the entire class.

Suddenly, a male student from the Department of Science and Engineering Computing spoke: "Shen Qi's algorithm is fine, but it is a little complicated, I have a more concise algorithm, I don't know if I should talk about it?"

Yo, there are masters in the Department of Science and Engineering Computing?

The students of the mathematics department all looked at this boy, yes, big brother, even Shen Qi, the little expert in pretending to be X in our class, dares to shout, it seems that you are also a pretending X thing.

Shen Qi smiled and looked at the boy who was in trouble, the boy with small eyes was also laughing, the two smiled at each other, hehe, come on, hurt each other.

The boy from the Department of Science and Engineering Computing was smiling all the time, his eyes were so small that they narrowed into a slit when he laughed, and it was difficult for others to observe his eyes, but what they saw was that there were two lines above his nose, representing his eyes.

In fact, this small-eyed boy looks like this, he may not be smiling, but his facial features are matched together, giving people a sense of déjà vu smiling all the time, his face shape and facial features are probably like this:

( ̄▽ ̄)

"I can say anything in my class, as long as it's related to math. Professor Lu, who had finished wiping half of the blackboard, turned around and said to the small-eyed boy, "Shao Tiantian, then tell me about your algorithm logic and core ideas." ”

Shao Tiantian said: "Professor Lu, I'll go to the stage and write it, soon, it'll be over in a while." ”

Professor Lu agreed: "Okay, you come up." ”

Of course, there is more than one algorithm for calculating reintegration, Shao Tiantian took the stage, picked up chalk and wrote his algorithm process on the blackboard.

Shen Qi knows Shao Tiantian, and has met several times in the past month, Shao Tiantian is the class leader of the Department of Science and Engineering Computing.

According to Shao Tiantian's oral account, when he was in elementary school and junior high school, he won the championship of mathematics competitions, and he had no pleasure in getting it, and even felt tired of mathematics.

Shao Tiantian didn't study mathematics seriously in the three years of high school, but even so, he was admitted to the Yan University School of Mathematics...... The authenticity of this dictation is yet to be confirmed. According to Shen Qi's judgment, Shao Tiantian's oral autobiography is similar to that of romance, seven points of truth and three points of fiction, I think he is bragging, and he can come up with some ironclad facts.

Shen Qi's solution process was originally written on the blackboard, but Professor Lu erased half of it, and the vacant space was left for Shao Tiantian.

Brush Brush Brush!

Shao Tiantian used his pen like flying, showing his strength on the stage of half a blackboard.

He applied the integral median theorem, the most basic method of processing fractions.

"The integral median value theorem, hehe, is interesting. Shen Qi maintained a highly concerned posture and watched Shao Tiantian's every move.

"Class Leader Shao, come on, write it, don't make a mistake!" The students from the Department of Science and Engineering Computing cheered for Shao Tiantian, they had all heard of Shen Qi's prestige, and Shen Qi had just shown a level in line with his name.

In a group of weak chickens, Shao Tiantian stepped forward, and he single-handedly carried the banner of the Department of Science and Engineering Computing.

"Class Leader Shao is a lonely hero, stand up for you! The banner of the Department of Science and Engineering Computing will never fall!" The students of the Department of Science and Engineering Computing were deeply moved and encouraged.

"Hey, hey, it's fun. Zhou Yu'an kept rubbing his hands, he was very excited, and he could enjoy the Yanjing fashion show again, if there was a bag of melon seeds at the moment, it would be perfect, it is said that melon seeds and fashion show are more compatible.

"The duel between the two squad leaders, who are you standing?" Zhou Yu'an asked Ou Ye in the seat next door, he came late, there was no seat in the classroom, only there was an empty seat next to Ou Ye in the back row, so Zhou Yu'an sat next to Ou Ye.

Ou Ye said two words: "Boring." ”

"Computing Ji, it's really boring to talk to you. "Zhou Yu'an likes to sit next to Shen Qi the most, but unfortunately he can only have a class with Ou Ye Jiang when he comes late.

Then Ou Ye added a few words: "He, it's okay." ”

"Is he okay? Who is he? Shen Qi or Shao Tiantian?" No matter how Zhou Yu'an asked, Ou Ye didn't speak anymore, she didn't look at the blackboard anymore, she lowered her head and played with herself, dealing with a bunch of complex numbers and symbols in the notebook.

Zhou Yu'an looked at the blackboard, Shao Tiantian used the integral median theorem to do some basic processing and foreshadowing, and then made a break in the Riemann-Dab sense.

"Yo he, yo hehe, Shao Tiantian's handling skills in the sense of Riemann-Dab, I didn't even expect it, there are two moments!" Zhou Yu'an looked at Shen Qi's position in the front row very excitedly, Big Guy Shen came out and suppressed it, someone rebelled, this person has some strength, it is a technical rebellion, and it should not be underestimated.

Shen Qi understood Shao Tiantian's thinking, overall it is not a big problem, Shao Tiantian's algorithm is slightly more concise than mine, there is nothing to show off, we are not in a hurry.

Soon, Shao Tiantian finished writing his algorithm and calculated that the answer was -8π, which was the same as Shen Qi's answer.

Shen Qi used almost an entire blackboard to solve the answer -8π, and Shao Tiantian only used half a blackboard to complete the same work.

There are two kinds of handwriting left on the blackboard, listing two algorithms with large differences, and they have the same goal, whether it is a complex algorithm or a concise algorithm, Shen Qi and Shao Tiantian's calculation results are correct.

Shao Tiantian explained what principle and path his algorithm was based on, then glanced at Shen Qi and stepped down.

Smack.

Professor Lu applauded twice: "Shao Tiantian's thinking is more ingenious, four or two thousand catties, bypassing a large number of calculations, and directly getting the results. I strongly advocate that students learn from each other in class, and the collision of ideas will inevitably produce great miracles. ”

"Yes, squad leader Shao, there is still this kind of operation?" The students of the Department of Science and Engineering Computing all admired Shao Tiantian and praised him sincerely: "Old Shao, it is simply a Tianxiu!"

Shao Tiantian smiled slightly and did not speak, and his eyes smiled into a double integral in the sense of Riemann-Dab.

Seeing this scene, Shen Qi shook his head and sighed, This can also be called Tianxiu? Have you ever seen the real Tianxiu? The learning atmosphere in your class needs to be rectified, Lao Shao, you have a great responsibility.
