My Identity As A Schoolmaster Has Been Exposed

Chapter 209 Lin Mengjiao broke the defense!

Although everyone returned to their seats, they still looked at him sympathetically, Yang Kaixuan was the first two people.

Sympathy to your sister!

Does Laozi study better than you guys?

Where did your flood of emotions come from?

“Usually I didn’t pay attention, but now I see Xu Cong and Yang Kaixuan sitting together, I still feel slowly!”

“One is looking for it, and no one is willing to participate…”

“Stop! Stop! Maybe it’s not! Maybe the school is looking for Yang Kaixuan!”

“However, there is absolutely no reason not to find Xu Cong!”

“What if people say that Xu Cong won’t participate! Who makes him so good!”

“Fuck!!! It’s really possible!”

Some people’s brain circuits are different. They brought many classmates to start various brain supplements, but they didn’t dare to directly ask Xu Cong face to face. That would hurt Yang Kaixuan too much.

Yang Kaixuan was completely speechless. Looking at these classmates, he felt like he wanted to die.

At this time Xu Cong turned his head and smiled and persuaded: “Don’t be familiar with them, I think you are very good, ordinary people, I am afraid that the teacher will find them, and they will not dare to go!”

Yang Kaixuan smiled bitterly, and said with difficulty: “Are you comforting me?”

Xu Cong waved his hand and said with a serious look: “No, I’m just telling the truth. For students with some emotions, I would really be unwilling.”

Yang Kaixuan sighed, with mixed feelings in his heart, it was really weird to be comforted by the last person who refused to participate in the competition.

So Yang Kaixuan changed the subject as soon as possible and said to Xu Cong, “Xu Cong, please advise me more in the future.”

“Maybe for those of us, it is hard to think about joining the training team, we can only rely on our own efforts!”

Lin Mengjiao leaned in at this moment and asked somehow, “Is there a big difference between this Olympiad and the test papers we usually do?”

She is Xiao Bai!

Xu Cong rubbed Lin Mengjiao’s brain, and went back very unceremoniously, “Aren’t you talking nonsense?”

Lin Mengjiao’s face was embarrassed: “Um…%￥##￥%….”

Yang Kaixuan looked at him, always feeling that these two people have a very good relationship, etc.

They won’t be the one, right!

I rely on!!!

I won’t be tortured like a dog when I get to the last row! Yang Kaixuan suddenly became irresistible.

He slowly raised his head, looked up at the sky at 45 degrees, and let out a long sigh: “Hey…”

Xu Cong saw his reaction and knew Yang Kaixuan’s thoughts in his heart.

Lin Mengjiao still said stupidly: “Uh…what is he doing? Is it the first time in history to sit in the last row.”

This is all secondary, okay!

The main thing is, you two cruelly abuse the dog!

It’s already very uncomfortable at first, but let me see you show your affection!

Yang Kaixuan, who has always been strong, really collapsed.

“Xu Cong, by the way, how difficult is the Olympiad? Is it different from what we normally learn?” Yang Kaixuan asked anxiously.

“The Mathematical Olympiad requires an understanding of mathematical concepts and theoretical ideas, and often requires special methods to solve problems.”

“Because the concepts involved in Mathematical Olympiad may be solved by mathematical concepts that students of this age have not learned.”

“It also requires students to use low-level concepts to solve problems based on high-level concepts. The process here can be equivalent to the process of mathematicians deriving high-level concepts from low-level concepts at that time.”

“It is not an exaggeration to say that Olympiad is used to train mathematicians.”

“Ordinary mathematics is to memorize concepts and formulas. As long as you apply the concepts and formulas you have learned, the focus is on cultivating mathematical literacy and application.”

Speaking of Mathematical Olympiad, Yang Kaixuan talked endlessly, all of which he learned from the website and some well-known personalities.

Xu Cong heard so much from him, and felt a little speechless in his heart.

He looked at Yang Kaixuan who was excited, and waved his hand to stop him, otherwise this guy would probably continue to talk about more theories.

“What you said is too complicated, let’s put it this way, Olympiad is not for more than 95% of the people in the world, but…actually, Olympiad is not too difficult.”

Puffy!

It’s not that difficult!

“Xu Cong, you can’t stand and talk because your back hurts!” Yang Kaixuan’s blue veins on his forehead violently jumped at this time, and the whole person was shocked by Xu Cong’s plain tone.

Xu Cong accidentally hit people again, a little embarrassed, but he still expressed his point: “Uh… it’s pretty simple, this thing has a small audience, but if someone is very interested, there are still signs. Followable.”

“For example, there are three typical and very basic thinking in Mathematical Olympiad: the principle of sum and difference, the principle of multiplication, and the principle of difference and multiplication.”

“Of course this is in the lower grades, but the upper grades are similar. Everything has principles and routines.”

“Master these, all problems will be solved.”

Yang Kaixuan listened to Xu Cong talking freely, clutching his chest, don’t get too excited.

Lin Mengjiao listened to the conversation between the two and really believed Xu Cong’s words. She muttered to herself… “So it’s like this…”

Such a wool!

Lin Mengjiao, can you make a basic judgment!

To be like what Xu Cong said, why is the only one in the school going to participate in the competition?

Yang Kaixuan felt tired for this silly Baitian in his heart, and at the same time he didn’t believe these words by Xu Cong even more.

“I seriously suspect that you did it on purpose!”

“Are you going to pull the dog over and kill it! Is it no longer enough to feed you dog food?”

Xu Cong turned to look at Lin Mengjiao who was squeamish, and said quickly, “Uh…misunderstanding, this is definitely a misunderstanding!”

Lin Mengjiao also nodded at the side of the chicken, “Hmm! Don’t get me wrong!”

Yang Kaixuan looked at the two with black lines, his fists clenched.

I don’t want to misunderstand, but you are really too much!

In order to turn this topic off as soon as possible, Lin Mengjiao hurriedly said: “Yang Kaixuan, can you show me the test paper?”

Get the Mathematical Olympiad paper!

Lin Mengjiao widened her eyes and said in shock, “200 points…”

Take a look at the title:

Given that i is an imaginary unit, how much is the complex number (1+2i)/(i-1)?

Lin Mengjiao suddenly burst into cold sweat on her brows, and said in a panic, “Uh…no…”

Let’s look at the next question!

Given that F₁ and F₂ are the left and right focal points of hyperbola C: (x²/9)-(y²/27)=1, and the coordinates of point A are (9/2, √135/2), then F₁AF₂ is the bisecting line What is the coordinate of the intersection point M with the axis?

“Hi…what kind of problem…” She frowned, and her heart became even more guilty.

I will always have one, she doesn’t believe in evil, look at it again!

Let f(x)=x2+bx+c, if the equation f(x)=x has no real roots, then the equation f(f(x))=x(?)

“Oh my God, what is this and what! I can’t understand that all the above are multiple-choice questions!

Lin Mengjiao didn’t even look at the options, because the title alone made her two big girls!

“I don’t believe it!”

Look at the fill-in-the-blank question again.

Given that (1-lcosxl)/(1+/cosxl)=sinx, then x=?

After Lin Mengjiao read a few questions in a row, her whole body was not good, her heart broke through, and tears began to fill her eyes.

She didn’t want to look anymore, she couldn’t stand it, she was afraid that her little heart would shatter.

Both multiple-choice questions and fill-in-the-blank questions are enough for her headache, and she dare not look at the latter questions.
