My Identity As A Schoolmaster Has Been Exposed

Chapter 229

Yang Kaixuan looked at him like this, with blue veins on his forehead violently, then calmed down and sneered: “You are giving up your humiliation!”

There were also materials and notes brought by Yang Kaixuan on the car. He took them out and opened a page at random. He pointed to the question above and said to this classmate.

“Look! Just this question!”

topic:

The function f(x) defined on R satisfies f(1)=2, and for any x∈R, f(x)=12, then the inequality f(log2x)-f(log2x+3)<2 What is the solution set of?

Seeing this question, the classmate laughed, and he passed the question to the other classmates. Everyone also smiled and shook their heads.

Yang Kaixuan saw how light they were, and said angrily: "Xu Cong can give an answer in one minute, can you?"

"Xu Cong's problem-solving ideas, I'm sure you haven't seen it before!"

"If you don't believe me, you can ask the two teachers to change the value of the question type. I will solve it according to Xu Cong's method. I must be much faster than you!"

Yang Kaixuan absolutely believes and admires Xu Cong!

"Is it that difficult for some people to admit that other students are excellent?"

Yang Kaixuan made a loud noise, the corner of his eyes twitched, and he said fiercely, "Compared!"

The teacher looks at the question, makes changes on the basis, and displays the question in front of everyone, "If you are interested, everyone has a try!"

"Paper and pen, everyone has it anyway!"

Some people have already begun to answer the question, and some people are so confused that they have no intention of looking at this question at all.

The dissatisfied student gritted his teeth and disdained Yang Kaixuan even more.

One minute!

He was still burying his head in two minutes!

Yang Kaixuan, "Teacher, do you calculate the answer is 0＜x＜4?"

One of the two teachers is also counting. After reading the questions, he is also starting to answer the questions.

Unexpectedly, Yang Kaixuan had already given the answer.

"Here you wait! You wait! Please wait!"

After more than a minute, the teacher looked up, and he said with an incredible expression: "Hey yes! That's the answer!"

And the student who was dissatisfied has not yet figured it out!

In fact, when Yang Kaixuan reported the answer, his mentality had collapsed!

Depend on!!!

The corners of his eyes twitched fiercely, and the veins on his forehead jumped wildly.

The teacher looked at Yang Kaixuan and said with a big smile: "Student Yang, can you share your problem solving process?"

Yang Kaixuan opened his mouth and said loudly: "This question can be set to g(x)=f(log2x), and then:…"

concise!

It's clear!

Many people understand it!

When one of the teachers saw this answer, he slapped his thigh and yelled, "Absolutely!"

Yang Kaixuan held his head high and said to them, "I learned these from Xu Cong!"

"Oh, if you still don't believe me, you can take a look at pages 7 to 11 of my notes! That question, I think teachers should be familiar with it!"

"This is the final question of the college entrance examination in a certain province many years ago! The average score of 300,000 candidates was 0.31!"

This question is very famous in the mathematics circle, because the influence was too great.

"There are several solutions for the answer alone, and I have sorted it out based on the ideas mentioned by Xu Cong!"

"So far, there are only complex and cumbersome standard answers on the Internet!"

"After all, the problem is not understandable at all, and no one wants to solve it! Teachers who talk about the problem will not talk about it!"

The two teachers opened the notebook and looked at it seriously.

One minute, two minutes, three minutes…

five minutes……

"Hey! Can this problem be solved like this? It gives me the feeling of discovering a new world!"

surprise!

"This is the second method! Let me go! There is still another solution! There is a third method.

"!!!"

"This Xu Cong is incredible too!"

"If you can have such a level, you are completely qualified to get out of the paper!"

This is the continuous discovery of the New World!

A series of surprises!

The two teachers looked at it several times, and finally reluctantly returned the notebook to Yang Kaixuan.

"Hi! Student Yang, please keep it away! Your notes are precious!"

Yang Kaixuan smiled and said, "But for Xu Cong, it's nothing, it's like saying-it's as simple as one and two!"

"It's a little bit more difficult. For him, it feels like multiplication and division!"

Everyone: "!!!"

The teacher asked: "Student Yang, is it stressful to be at the same table with such a person?"

Yang Kaixuan smiled bitterly, "Although I can't compare to everyone here, I was the number one in our school before, and for a long time, I have been the number one! Now, I have no temper at all!"

"There is no comparison between me and him, so where is the capital under pressure?"

This day is destined to be the nightmare day of many top mathematics students across the country!

But for Xu Cong, today, he had a good time, after all, this is what he really meant to come out to play.

But the only thing that made him a little uncomfortable was that he was surrounded by a group of elderly people, all kinds of boasting, changing the way to boast, and boasting wildly!

The words to their lips, three lines of praise Xu Cong, people who don’t know, thought Xu Cong was the only grandson these old people grew up watching together!

This is the benefit of the question group. After the question is finished, they can come out to play. This is arranged by the organizing committee.

They went out to travel and climbed the mountain. At this time Xu Cong was surrounded by a group of elderly people again.

"Student Xu Cong, your physical strength is really good! We can't do it! Huhuhu…Go by yourself! We are waiting for you halfway up the mountain!"

Xu Cong looked at the group of old men, smiled, and then quickly walked up three steps in two steps, and he was not afraid of heights, nothing terrible.

Seeing Xu Cong walking fast, the twilight old people cast envious eyes.

"I'm jealous!"

At this time, Xu Cong climbed to the top alone, and now it is off-season. Few people come here for work, work, and school. Therefore, for Xu Cong such a special existence, don’t mention how cool it is!

Soon, he easily came to the top of the mountain, Xu Cong looked at the mountains and the beautiful scenery in the distance.

The middle-aged man next to him saw him coming up by himself, and he looked so young again, and asked in confusion, "Little friend, are you a college student? So have the time?"

Xu Cong smiled faintly when he heard the words, and said to him: "High school student."

"High school students?! Shouldn't high school students be in school at this time? Did you ask for leave? Or did you sneak out?"

Xu Cong thought for a while, but didn't tell him the truth, "It's a leave!"

The middle-aged man gave him a thumbs up, and said to him: "The young people are really free and easy now! But I followed you all the way up, right? They are…?"

"Moreover, they don’t look like ordinary old people in their looks and conversations. Even if they are old, they are very temperamental."

PS: I pushed a book, a new book written by an author I know, I read it pretty well, you can check it out.

Title: Headmaster, I really didn't want to confess to you!
