Chapter 17: Let him finish pretending

Yan Xiaoxi almost vomited blood. What do you mean I don't know? I asked all these questions.
"I came up with all these questions. Do you think I can do it?" Yan Xiaoxi pursed her lips, showing an expression of disbelief on her face, and said lightly: "You think it's easy? Don't brag. This question looks simple, but it's actually incredibly difficult. I bet that there are no more than ten high school students in the country who can solve this question."

"is it?"

"But I really don't think it's that difficult." Chen Xiaoxin looked carefully at the questions on the white paper. One was to find the monotonic interval of f(x), and the other was to prove that 1
Yan Xiaoxi rolled her eyes and said unhappily, "Then you will know after you try it. Don't cry when the time comes. By the way, I have two solutions. If you can solve one of them, I will admit defeat and accompany you to fight the dungeon in the future."

"Row!"

"A word is settled!"

Chen Xiaoxin picked up the pen and started solving the problem.

The first question is actually an easy one, and you can solve it with your eyes closed, but it happens to be a trap. Yan Xiaoxi cleverly placed a very confusing answer in it. However, for Chen Xiaoxin, it was all too simple and he could see the clues at a glance.

Yan Xiaoxi looked at him quietly, and couldn't help but smile as he figured out the answer to the first question. She secretly thought to herself, "You're still a little naive. Do you think you can figure it out so easily? What are you going to do next?"
However.
What Chen Xiaoxin did next made Yan Xiaoxi drop her jaw.

What!
He actually discovered it?

No. No way? It's fake! It must be fake!

But it turned out that Chen Xiaoxin did find her trap. After finding the answer to the first question, he immediately reorganized the entire question, setting B equal to eight times ax, proving that one is less than the square root plus X, and then using the proof by contradiction to prove that P plus Q plus R is between 1 and 2, thus proving its upper bound.

Me. Oh my god!

He just glanced at my topic, then picked up the pen and started writing, and then he did this step!

Yan Xiaoxi almost doubted her life. She had been thinking about this question for ten minutes and finally came up with the answer after repeated deductions. Unexpectedly, her classmate Wolong took a look at it, picked up a pen and dug out the trap she had set.

遭了
Next, using basic inequalities, we can directly deduce the conclusion that is greater than or equal to two.

A complete defeat! No, a miserable defeat!
Yan Xiaoxi was shocked, angry, and at a loss. At the same time, she was very confused. He was obviously a great math genius, so why did he always rank last in previous exams? Did he not want others to know that he was a genius? If that was the case, why did he suddenly start to show his talent again?

Is it
Was it because of my appearance? Did he realize the crisis? That's why he showed it?
Yan Xiaoxi was constantly working on herself, while Chen Xiaoxin on the other side was almost done. After he wrote down the last character, he turned around and looked at his deskmate next to him.

"it's over"

"Shall we meet at nine o'clock tonight?" Chen Xiaoxin asked.

"."

"Give me 30,000 gold coins and I will accompany you to play the dungeon." Yan Xiaoxi curled her lips and said with an unhappy look on her face.

"it is good!"

"Then it's a deal."

Chen Xiaoxin nodded with satisfaction and whispered, "Actually, I also know the second solution, which is to prove it by comparing local inequalities. Of course, I can also use the third method to solve it. Writing the formula in reciprocal form and finding the common denominator can give a result equal to one, but it requires algebraic transformation, which I don't think is appropriate."

Right now,

Yan Xiaoxi's self-esteem was severely hurt, and she also felt ashamed of what she had said before. She never expected that the clown was actually me!

In fact, Yan Xiaoxi also knew the third solution, but she felt that with the level of her classmate Wolong, he would not understand even if she told him, so she simply did not mention it. However, he brought it up even though she did not mention it. She had come up with the question, but he finished it all.

I. I am so angry!!
I glanced at him out of the corner of my eye and found that my classmate Wolong was eating snacks secretly again, and then playing games quietly. I used to look down on him, but now... I strongly despise him!
Although he is a genius hidden among the crowd, this cannot conceal his nature as a parasite.

But then again.
Since he is so good at math, he should be strong in physics as well, right?
Forget it
I'd better focus on my studies. The relationship between him and me is limited to being desk mates and comrades in the game. There will be no other relationship.

Night study,
As usual, it turned into a class.

The math teacher was explaining the problems on the stage, and the students below were concentrating, except for two people. They were doing their own things. Yan Xiaoxi was flipping through his books, immersed in the ocean of knowledge, while Chen Xiaoxin was playing games next to him, immersed in the pleasure of killing a kid with one knife.

Strange man
Yan Xiaoxi glanced at her deskmate Wolong and felt confused. He was obviously very good at playing Honor of Kings, but he just slacked off every day in World of Warcraft. They are both games, so why is there such a huge difference in his performance?

in fact
Chen Xiaoxin actually tried to slack off in Honor of Kings, but he couldn't resist the thrill of bullying and his competitive spirit, so he gave up those insignificant points in exchange for the pursuit of victory. In general, Chen Xiaoxin likes PVP but not PVE.

Including in World of Warcraft, although his performance in the dungeon is very poor, he is like a god on the battlefield.

"Eat?"

Chen Xiaoxin handed her a piece of chocolate and whispered to her, "New flavor."

Yan Xiaoxi ignored him and continued reading the book. However, when the chocolate was about to be taken back, she suddenly reached out and snatched it away.

of course,

She would never eat during class and would wait until the get out of class was over before eating.

"Do me a favor." Chen Xiaoxin said in a low voice.

"No time."

Yan Xiaoxi didn't want to pay any attention to him and refused coldly with a dark face.

"."

"Give me back the chocolate." Chen Xiaoxin said unhappily.

"No!"

Yan Xiaoxi rolled her eyes at him and replied calmly, "You can't take back something you gave away. Don't you understand?"

Looking at his angry and helpless look, Yan Xiaoxi felt so relieved in her heart, as if she had avenged herself. However, her happiness did not last long. She suddenly realized a problem.

what's the situation?
Is this satisfying enough?

The threshold for happiness is too low!
Yan Xiaoxi bit her lips tightly and secretly complained in her heart, Yan Xiaoxi, Yan Xiaoxi, you are a super academic master, you can't lose yourself because of a little victory.

As the bell rings for the end of get out of class
Yan Xiaoxi unwrapped the chocolate and put it in her mouth.

So sweet!
