I really don't want to lie down and win

"We can't let them just follow the formulas, bring in a few numbers, and then just do the math, that's not acceptable!" Xu Mang said: "We need to let the students think about a question, why do they need to use calculus, why use linear functions. "

"Not only that, but I also plan to make the topic more international. After all, our students are going to the world stage, so let them adapt in advance!"

"Teacher Teng!"

"The scores of this year's class may be so miserable that they can't be seen directly." Xu Mang said seriously, "Be prepared for a crash."

Miserable?

Shouldn't be possible.

Teacher Teng still has confidence in the players from Zhejiang Province. It is a bit difficult to get a perfect score, but it should be no problem to get half of the score.

"Teacher Teng!"

"Our mathematics environment is very bad. Whether we can change the environment depends on your decision!" Xu Mang added emphatically.

"..."

"Don't put a high hat on me, you boy." Teacher Teng thought for a while, and said to Xu Mang, "I have confidence in the students in our province, and it is impossible to wipe out the entire army...Then follow your ideas!"

Xu Mang showed a slight smile: "Okay!"

Chapter 325 Difficulty Advisor (1/3)

Xu Mang was quite unlucky. He originally thought that there would be a big group behind him, not to mention thirty professors, at least five associate professors, right?

result...

A polished commander, the majestic Zhejiang Provincial Mathematical Olympiad Competition, only one person wrote the question.

According to Mr. Teng, many people decided not to participate after they knew you were the one who made the question. Anyway, it’s useless to go in by themselves... It’s really sad to hear, and those who hear it cry.

In the temporary office,

Xu Mang lay on the chair, crossed his legs, with a bottle of iced black tea beside him, with a contented expression on his face.

There are ten days left,

Don't panic!

"Hey?"

"Have you returned to the Magic City?" Xu Mang received a call from Yang Xiaoman.

"Go back tomorrow."

"You're already at Jiangda?" Yang Xiaoman said, "Well...I met a lot of people, and everyone praised us, but I feel...a bit of a conscience, in fact, these credits are all your."

"It doesn't matter."

Xu Mang stretched his waist, and said silently, "I'll hang up first... I have to work."

"Um..."

"Kiss me!" Yang Xiaoman said greasyly.

Xu Mang froze for a moment, then silently pressed the end button...Looking at the interrupted call interface, he smiled.

Kiss a yarn!

Do you have the ability to hit me? !

jobs!

First of all...it's the topic of the individual competition.

Since it is an individual competition, it is an occasion to show personal strength.

Xu Mang bit the tip of his pen, his brows were furrowed. According to international practice, the first question is a sub-question. Usually, some points are given to the contestants so that they don't lose too embarrassingly. Difficulty needs to be changed.

Send sub-questions?

Why is the first question a sub-question?

Which bastard prescribed it?

Xu Mang thought about it carefully. There don't need to be too many questions, but each question is just a proposition.

first question,

Xu Mang decided to use geometry directly!

In the convex quadrilateral ABCD, ABCDBCDA, the point X is inside the quadrilateral ABCD and satisfies angle XAB, angle XCD, angle XBC and angle XDA.

Prove: Angle BXA Angle DXC Flat Angle

"hey-hey..."

"Yes, yes!" After Xu Mang finished writing the first question, he even laughed to himself. This is the devil!

"Ugh..."

"Xu Mang?"

"You're so handsome and smart, how can you let other young men in the world live?" Xu Mang sighed, with sadness written all over his face.

Then,

Xu Mang started to write the second question.

A primitive lattice point is an ordered integer pair x, y, where the greatest common divisor of x and y is 1, given a finite primitive lattice point set S, prove that there exists a positive integer n and integers a1, a2 , a3...aN, making it true for each x, y in S: a0xna1xn1ya2xn2y2...an1nxyn1anyn1

°ー°〃 in meditation

‵′Hey hey hey

Xu Mang was overjoyed.

This kind of question can basically be called an anti-human question. If you don't have strong thinking ability and don't understand the concept of mathematical formulas, then you will definitely go to zero and don't even need to look back.

genius?

Sorry,

Do at most two questions!
