Chapter 222

Sage A kind of In the forest.

Cheng Nuo: "did the senior mathematics teacher call the roll? @Yuan Hua "

Yuan Hua:" no, I'm ready to start talking about Yuan Hua: "brother, you won't Prepare to skip class! "

The beginning of higher algebra, however, did not prevent him from attending the class.

In other mathematics departments, students think that a fast lecture speed is just right for Cheng Nuo.

On the platform, every time Mr. Liao talks about a formula or concept, Cheng Nuo can master it quickly.

Those examples and so on, Cheng Nuo basically glanced at them and calculated them in his mind. The steps are basically not too much different from what the teachers of the higher generation said.

As for notes or something, they don't exist! It's impossible to take notes. You can't take notes in your whole life. You can only rely on the occasional full score to maintain the life.

Brain! Is Cheng Nuo's best notebook! Want to use what knowledge points, do not bother to turn over notes, directly from the mind out of the line.

Oh! No way!

Cheng Nuo sighed. Under the aura of learning hegemony, he is so corrupt that he is helpless!

Cheng Nuo also took advantage of Mr. Liao's teaching time, drank saliva, and chatted for a while. Look up, roughly scan the formula on the courseware and blackboard, and you will be able to keep up with the progress of higher generation teachers.

You can enjoy yourself and enjoy yourself!

In the whole classroom, I'm afraid only Cheng Nuo is alone. It's so relaxing.

The most terrifying thing is, Cheng Nuo It's a finance student!

Liao Zhi's trip to higher algebra took less than half an hour to finish.

Yes, indeed, it only took half an hour!

This is the legendary Tsinghua speed!

In the eyes of the students in the mathematics department, it's not so much the end of the lecture, but it's just a thread from the beginning to the end.

In theory, they had a general idea.

But when it comes to actual combat, to do specific topics, whether they can skillfully apply these theorem knowledge is still a pseudo proposition.

On the platform, Liao Zhixing threw only a small piece of chalk to the lecture table mountain, rolled up his suit sleeve and asked the crowd with a smile. "Do you understand what I'm saying?"

"I understand..."

"No..."

Two different voices were heard below.

Liao Zhixing faintly smiles, "do you think that the speed of my lecture is a little too fast?"

Everyone nodded, except Cheng Nuo.

Liao Zhixing gently shook his head, "no, no, it's not that I speak fast, but you understand too slowly. I just saw that when I was lecturing, many students were immersed in taking notes. On the contrary, very few people have been holding their heads up. "

"I don't object to you taking notes, but you should always take notes with emphasis. Don't tell me what to say, just remember what I say

"And..."

It's OK, bar ~

Liao Zhixing talked about a lot of things with painstaking effort, "at present, this speed is only the most basic speed. If it's not for fear that you can't keep up, I'm going to finish half of the book in one class

One class, half a book!

The whole class had an idea of dying.

Although, they are from the country's millions of examinees out of the learning bully. But it's just ordinary people!

A class half a book, even if is called this year's college entrance examination champion came, may not bear it!

"Well, no matter what you understand or what you don't understand, let's practice with two questions first." Liao Zhixing opens a PPT, which presents a problem:

find all complex coefficient polynomials satisfying f (x? - f (x) f (x + 1) = 0.

The title is short, and at first glance it seems simple.

But often, the simpler the problem seems, the more difficult the calculation will be.

"This topic is a little difficult. You can do it first. I'll ask my classmates to answer it later." With that, Liao Zhixing took a cup of bubbling wolfberry and sipped it.

Can be Tsinghua teachers are called the difficulty of the problem, the difficulty coefficient, absolutely can not be underestimated!

This is a stubble!

However, since they choose to apply for the Department of mathematics, they are ready to meet many difficult mathematical problems.

Under the platform, students of mathematics department took out paper and pen one after another, lowered their heads, frowned, and shuddered on the paper.

In the classroom, except for the sound of the pen tip and paper friction, no other sound can be heard.

The chubby classmate with beard is also writing and drawing on the paper.

Although he didn't understand much of the content before, he didn't know what he was calculating.

After a minute, the fat students threw the paper aside.

When I turned around to see the progress of other students, I suddenly saw the figure sitting beside him, who was completely in two worlds in the surrounding environment -- Cheng Nuo!What makes pangpangpang wonder is that Cheng Nuo, sitting next to him, seems to be unmoved when other students are all immersed in solving problems. Hold your head with your hand and your eyes wander. On the desk, there was nothing but a notebook. No textbooks, no pens.

And the notebook, is also a blank.

This makes the fat students doubt how the guy next to him came to Tsinghua University.

I've tried my best to hear it! Although Is still a tragedy, did not understand! But after all, I tried my best!

But you don't even take textbooks, take notes, do not do the topic of the guy, a little too much ah!

I'm still in class now. It's not convenient.

Fat students decided that after class, we must preach and teach. We should let Cheng Nuo know his way back. We should not neglect our studies and become a useless person to the society.

Five minutes later

There are still ten minutes to go before class is over.

Liao Zhixing stopped all the answers. He held up the table and asked with a smile, "OK, is anyone willing to volunteer to come up and solve this problem?"

Silence, the silence of the needle.

No one raised their hands, no one answered.

Liao Zhixing's face was slightly embarrassed. "It seems that everyone is shy."

"In that case, I'll call one of my classmates at will!"

With that, Liao's eyes swept around the classroom.

Did not solve the problem, the heart of the fat students, low head, like an ostrich, would like to head down to the soil.

Liao Zhixing's eyes, after scanning the classroom for a week, suddenly fell on the fat students.

The fat classmate who is lowering his head, inexplicable feeling chrysanthemum suddenly a tight.

"Come on, that fat classmate, come up and tell us about this problem."

The fat classmate looked up, looked around and pointed to himself.

"Yes, yes, it's you, the fat classmate with glasses!" Liao Zhixing opened his mouth with a smile.

Fat students a face very reluctant to get up, standing in the same place.

"This fat classmate, let's share your solutions. We can make progress together only if we pool our ideas together. " With that, Liao Zhixing looks at the fat classmate with encouraging eyes.

The fat classmate hesitated for a moment, and said bravely, "teacher, I I won't! "

"No?" Liao Zhixing was stunned, "this By the way, what's your name? "

"Li xiurui." Fat students speak in a weak voice.

"Chubby Li xiurui, yes, I'll call you later."

Li xiurui has a black line.

Teacher, you can just call me my name directly. The two modifiers in front of you are not needed

"You shouldn't be!" Liao Zhixing walked back and forth on the podium, teaching dundundundun, "it's good that this problem is difficult, but as long as you understand what I've said before, you can understand it thoroughly. It's OK to make this topic."

"Teacher, I..." Li xiurui said.

Liao raised his hand to stop, "if you don't believe it, please call another person in our class to see if he can solve this problem. If not, it means that I have a problem with my teaching speed. If I can, it means that your basic knowledge is not solid enough. "

"Then I'll choose him!"

Li xiurui reached out and without hesitation, chose the one sitting next to him Cheng Nuo!
