I really don't want to lie down and win

The professor and Xu Mang came in, and they stood in front of the podium. The professor said, "I guess everyone has guessed it. The question that stumped you all was made by this classmate, and this classmate came from the review center." Big, his name is Xu Mang, you should have heard of it."

"Extraordinary achievements have been made in the field of physics, two academic papers in SCI Area [-]." The professor said, "But don't forget that Xu Mang's mathematical talent is the same as his physics."

"Xu Mang?"

"Tell them the way to solve this problem, and I'll take the class by the way." The professor smiled at Xu Mang, and then walked down the stage.

Yang Xiaoman was about to say, professor...you will regret it, but the professor went directly to the stage without any melancholy.

Seeing Xu Mang on the stage with a smile on his face, Yang Xiaoman's head grew big...Don't make your teammates shut up, it won't hurt!

"classmates!"

"This question is very basic and not difficult at all." Xu Mang said with a smile, "This is a sub-question!"

As soon as the voice fell,

The four students present were very angry, and they planned to raise the knife.

at this time,

Yang Xiaoman: °ー°〃

It's over,

He's about to start!

......

Chapter 3 introduces Xu Mang into the house (3/3, add more for WERobin)

After hearing Xu Mang's words, the few people felt a little helpless in their anger, and made the question so difficult that they were about to collapse, but in Xu Mang's mouth, it became a sub-question.

Sorry,

Self-esteem cannot accept such a result.

"Really!"

"This is really a sub-question!" Xu Mang said with a smile: "Maybe you will think that this question looks difficult. After writing and drawing a lot, you find that you can't advance at all. That's because Your mathematical thinking is not up to the mark."

"At your level, you have fully mastered the basics of mathematics, so don't do the quizzes." Xu Mang said seriously: "The quizzes are for people who have not mastered the basics of mathematics. These people can use the quizzes to consolidate their foundation, but You need to improve your mathematical thinking, not your mathematical foundation."

Xu Mang paused for a moment, then said with a smile, "Haven't you seen this function before?"

words fell,

I saw a few people nodding.

"Actually..."

"This is a common function." Xu Mang said, "It's just hidden and needs to be evaluated."

At this time,

Xu Mang picked up the chalk and wrote down the simplest and most standard problem-solving process. There was no sloppy behavior in the whole process, and he went directly to the answer.

of course,

There is a change in the process, and that change is the key to the final answer.

"You should understand it before, but here...you may feel confused, let me explain briefly." Xu Mang said: "This function takes values ​​at any three adjacent points of n, n1 and n2 An arithmetic sequence is formed, so the tolerance of this arithmetic sequence is that fn1fn is a constant."

"This is the most important point!" Xu Mang said solemnly, "Because only when you calculate to this point, can you know that this function is actually a linear function."

"under..."

"You can deduce it yourself, it shouldn't be a problem, it's all a matter of course." Xu Mang smiled: "Simple, right?"

"..."

"..."

"..."

Not to mention,

After such an analysis, it is so simple!

The five contestants, including Xiaoman, were completely overwhelmed by Xu Mang's IQ to the point of doubting their lives. Why is this problem so easy in his hands?

It is easy to deduce that the function is a linear function...

The professor glanced at Xu Mang on the stage, and then at the silent and helpless contestants in the audience. He silently decided to kick Xu Mang out. There was no way...Although what Xu Mang said was true , this topic has indeed become very simple after his analysis, but...

Sorry,

Still have to drive out.

If you don't get kicked out...I'm afraid the players will all be autistic.

"Then what..."

"I..."

"Xu Mang!" The professor hurriedly stopped his next words, got up and said, "Come out, I'll tell you something."

"Oh..."

moment,

Xu Mang was led to the corridor by the professor.

"professor?"

"What's the matter?" Xu Mang asked dumbfoundedly: "Just now I thought of a classic question type, about a geometry, please feel it first, in the acute triangle ABC, I is the heart, AB is not equal to AC, triangle A..."

"Stop, stop, stop!"

The professor said helplessly: "This topic is very interesting and requires thinking skills. It is really good."

"..."

"But I haven't finished yet." Xu Mang said with a confused face, "Professor...do you have the ability to foretell?"

"Xu Mang?"

"what?"
