Chapter 222 (1/2)
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!
