I Just Want to be a Shenhao Quietly

For a moment, everyone in the classroom was full of black question marks

Nima, we saw you sitting in the student seat, why did you become a substitute teacher in an instant?

Is this an insult to our intelligence?

Suddenly, there were whispers in the classroom.

"Fuck, who is this buddy?"

"Hey! What a handsome little brother, talk about a professional? Why haven't I seen it before?"

"I think he might really be a substitute teacher!"

"Why do you say that?"

The reason is very simple. I have seen all the handsome guys in our big class. But this handsome guy is very unfamiliar, it's the first time I've seen him. "

"I'll go, this skin is too good!"

...

"Quiet!"

With a straight face, Lin Xian knocked heavily on the podium a few times.

Seeing his serious face, the students shut their mouths involuntarily, and the classroom became quiet again.

Seeing this scene, Lin Xian couldn't help but nodded in satisfaction, and said, "Professor Wang talked about Lagrange's median value theorem in the last class. Let's continue today."

Not to mention, although Lin Xian is young, he has an outstanding temperament, coupled with his tone and demeanor, he can't help but be convincing.

Ever since, these students opened their books one after another.

If you change to the old fritters who are juniors, juniors and seniors, you really can't fool them.

However, these students are just freshmen, they are still very simple, and their way of thinking has not changed from high school, so they are easy to deceive.

As for the substitute teacher, why did they sit in the student's seat before, these students felt that they were probably observing their discipline

Hmm, well thought out.

Yan Xiaoman and Zhou Hui were completely dumbfounded when they saw the students who were sitting beside them sitting upright and listening to the class seriously. Is this okay?

But soon, Yan Xiaoman came back to her senses, with a playful smile in her eyes.

Even if you pretend to look like you, what's the use?

Could it be that you still...

Damn, it really does!

In the next second, Yan Xiaoman's eyes widened, and he fell into a daze again.

On the podium, Lin Xian picked up the chalk, quickly wrote down a line of formula on the blackboard, and then talked freely.

The point is, he lectures without script, without even a textbook, and relies entirely on a piece of chalk.

Chapter 38 This kind of thing is addictive!

"Lagrange's mean value theorem, as the name suggests, its prover is Lagrange." Lin Xian paused, wrote Lagrange's name on the blackboard, and said with a smile: "In the world of mathematics, Theorems and conjectures are generally named by the names of the proposers and provers. In the future, if you see the name of an unfamiliar mathematician and want to know whether he is awesome or not, it is very simple. You only need to recall whether it is named after him. Mathematical conjectures or theorems will do.”

"Although not all great mathematicians have proved or proposed conjectures and theorems. But mathematicians who name conjectures and theorems after them must be very good!" Hearing this, the students in the classroom all smiled knowingly .

They felt that the substitute teacher was not bad, and his speech was very interesting, not boring at all.

"Before explaining the theorems, let's get to know this mathematician first. Lagrange is a French mathematician. He studied under Euler, the first person in mathematics at that time. In the current online novel, the Holy Son or Daozi's candidate."

Hearing this, the students couldn't help but smile again.

Holding the chalk, Lin Xian rolled up the cuffs of his windbreaker slightly. With a confident smile on his face, he talked eloquently: "He has made important contributions to the theory of equations, the theory of solving string functions, and number theory. Lagrange The median value theorem is one of many achievements. Well, after introducing the prover of the theorem, let's take a look at the conditions of this theorem at this moment..."

At this moment, Yan Xiaoman looked like he had seen a ghost.

My scumbag boyfriend is now giving her a lecture, and the key point is that she speaks very well.

This tm... Who will believe it!

All are hallucinations.

It must be the wrong way for me to open it!

Thinking of this, Yan Xiaoman closed his eyes, took a deep breath, and then opened his eyes to Xin.

In sight, it was Lin Xian on the podium.

At this moment, Lin Xian was staring at her, and said with a half-smile, "Student Yan Xiaoman, please answer the question about the relationship between Lagrange's mean value theorem and Taylor's formula."

Yan Xiaoman: ???

She had been in a state of confusion just now, her mind was full of question marks, and she didn't listen carefully to what Lin Xian was saying.

Seeing her dumbfounded and unable to speak, Lin Xian smiled badly and said, "Listen carefully in class and don't get distracted. I don't want you to be the worst student among the worst students I have ever taught."

The worst of the worst class?

Many students couldn't hold back and laughed out loud.

hiss!

Yan Xiaoman was so angry that her teeth itched, she kept grinding her little tiger teeth, and a dangerous light flashed in her beautiful eyes.

If it weren't for the inappropriate current situation, she would definitely bite the bastard to death.

This bastard actually made himself ashamed in front of so many classmates.

Hi, so angry!

But apart from being annoyed, Yan Xiaoman was more shocked.

The calm and eloquent person on the podium is really his scumbag boyfriend?

If this TM is a scumbag, then what is he?

Xuemo?

Or disabled?
