Xueba, I beg you to go and escort him quickly!

On the contrary, I will like it very much.

Xu Heng knows one thing very well, as long as you don't cause trouble, everyone is still very tolerant of you.

In the examination room of Peking University.

There are many desks and many professors.

However, Zhu Tiesen and the others were the leaders, and they all surrounded Xu Heng.

Xu Heng looked around and found that there were more than 20 teachers in the entire examination room, and the youngest was more than 40.

Except for Xu Heng, everyone, without exception, wore thick myopia glasses.

"Student Xu Heng, sit down!"

"Everyone sit down! Let's have a meeting first."

Today's meeting started with Zhu Tiesen as the leader.

"This year's Mathematical Olympiad will have relatively different questions."

"Of course, the same thing is that the students can't understand it... even if they understand it, they can't do it..."

"As for whether you can cry them in the test...it depends on everyone's ability!"

"..."

"Student Xu Heng, as a member of the examination team, you can't show mercy!"

brush!

Everyone looked at Xu Heng.

After a morning of understanding and understanding.

Xu Heng has already conquered everyone present with his ability.

On the huge four-open blackboard, Xu Heng wrote down a lot of ideas for solving problems.

it's here.

There are basically no topics that can be stumped.

A solution, anyone can.

But two, some people frowned.

What about three...

What about four...

Xu Heng stopped because he couldn't write on the blackboard.

Therefore, in the hearts of these people, Xu Heng is better than any student they have ever seen or taught!

Even if they have taught various champions and even the best in international mathematics competitions, they will not be as shocking as Xu Heng.

Seeing the gazes of the people on him, Xu Heng said calmly, "If you are not in your position, you will not seek your own affairs, but if you are in your position, you will seek your own affairs."

"I hope that the question I propose at that time will not be too difficult to be voted on, so I will give up using it."

As soon as this remark came out, all the professors laughed.

"Student Xu, please show mercy! Try not to make it too difficult!"

They were sincere, because during the whole morning of contact, Xu Heng gave them the feeling: This is also simple, that is also simple, no matter how simple it is...

It seemed that Xu Heng was telling everyone, "I'm a sophomore in high school! I know all these things, it's very simple! Are these questions, and the face, put on the test paper of the National Mathematical Olympiad?"

"Simple!"

"Easy! I can have three solutions!"

"Are you sure, this is the real Olympiad question? You're not kidding."

"..."

After the meeting.

Jutson called Xu Heng aside.

"Student Xu Heng, you have to proceed according to the actual situation!"

"We also have an outline for our questions..."

Xu Heng, "I also followed this way, but the way of solving the problem is a bit different!"

Zhu Tiesen was speechless for a moment.

He really couldn't find anything to refute Xu Heng.

Xu Heng made the questions according to the requirements, and they were all within the scope, but it was very frustrating to do it!

It was a headache for Zhu Tiesen to do these questions by himself, let alone those examinees.

"OK! OK..."

"You played normally! You played your normal!"

Zhu Tiesen was speechless!

Xu Heng, "Then I'll go get busy."

Back at his desk, Xu Heng continued to analyze the various question banks, looking for question types that would catch his eye.

Several old professors flocked to Zhu Tiesen.

But everyone's eyes stayed on Xu Heng.

Among them are Fuda, Zhongke, Nanjing University, and several other professors with extremely high levels of mathematics.

They looked at Xu Heng like a wolf who had been hungry for four or five days and found a fat rabbit.

Zhu Tiesen looked at these people and immediately felt that something was wrong.

"Hey, hey! Old guys, what do you mean?"

"Xu Heng is now the one who produces the papers! It's not what you want to fight for..."

Not finished yet.

The old professor from Nantah University went to Xu Heng.

In front of these people, he was very active and smiling.

"Student Xu Heng, Lao Zhu's words are a bit heavy! But don't put pressure on yourself! You can do it anyway. If you can come up with such a topic, I definitely agree."

Depend on! ! !

I, Zhu Tiesen, sing bad faces, but you are good, and ran to sing bad faces in a few minutes!

Your idea of ​​fighting for Xu Heng on behalf of Nantah University is too obvious!

"Sima Zhao's heart is known to everyone!"

"This old boy is a bit shameless!"

"It is! It is! It is!"

"Excessive!"

These few mouths are full of righteousness.

Zhu Tiesen almost believed it!

"It's up to you to talk, but why do you want to go to Xu Heng's side!"

Could it be that Xu Heng has a magnetic field on his body?

???

Zhu Tiesen had black lines on his face.

"Yes! Student Xu Heng, don't be as knowledgeable as Lao Zhu!"

"Old Zhu is a bit rigid, but he has no bad intentions!"

"..."

Zhu Tiesen didn't want to swear, so he almost couldn't hold back!

You guys are too realistic!

In order to please Xu Heng, are you too shameless!

One by one!

unacceptable!

Zhu Tiesen looked like he hated iron but steel, "If 30 years ago, I would have rolled up my sleeves and fought with you!"

"The bad guys let me do it, but you guys are better off, one can pretend to be a good guy than the other!"

Everyone valued Xu Heng's mathematical talent!

The old professors of these universities represent their respective universities, and they all want to poach Xu Heng!

Not only Peking University, Fuda University, Nanjing University, and Chinese Academy of Sciences, they all want Xu Heng to enter the mathematics department of their university.

Xu Heng looked at the old professors in front of him and smiled bitterly.

"Everyone, I'm busy! I'm busy..."

Xu Heng was very clear about their thoughts.

But Xu Heng doesn't care about these things now, the most important thing is to get the things in hand done.

The earlier the problem is solved, the earlier the salted fish can be.

"What do you guys think of this question?"

Suddenly someone stepped forward to clean the blackboard and wrote his own topic on it:

在平面直角坐标系xOy中，椭圆C：（x2/a2）+（y2/b2）=1（a＞b＞0）的左、右焦点分别是F1、F2，椭圆C的弦ST与UV分别平行于x轴与y轴，且相较于点P。

Given that the lengths of the line segments PU, PS, PV, and PT are 1,2,3,6, 1, 2, and [-] respectively, what is the area of ​​△PF[-]F[-]?

A fill-in-the-blank question.

Everyone looked at the blackboard, weighing the value of this question.

For Xu Heng to bow his head to write and draw on the paper, every minute...the answer came out.

"The root sign is 15."

Xu Heng was whispering, when a teacher at the side suddenly heard it, and asked sideways, "What's wrong? What's the square root of 15?"

Xu Heng, "Huh? It's all right..."

"Oh oh oh!"

The other party didn't take it seriously, and listened to everyone's analysis of this question.

Several old professors looked at each other and nodded.

"It's really good! Give me the idea and process of solving the problem together!"

The teacher started the writing process step by step, and finally gave the answer.

These people in the test group are not just as simple as just asking questions, they also have to give corresponding and reasonable answers.

"According to the symmetry, we might as well set p(xp, yp) in the first quadrant, then we know from the conditions..."

"..."

The answer to a fill-in-the-blank question turned out to be the steps of a calculation question in the usual general exam.

There are as many as six or seven lines.

"BC=root sign (OB2+OC2-2OB*OC*cos∠BOC)=root sign 10..."

　 　"..."

"Finally, I got the answer under the square root of 15!"

When the final answer is written.

The teacher next to Xu Heng was surprised, "Have you shown this question to Xu Heng?"
