Xueba: The Knowledge I Teach, The Crit Is Returned

"Fuck....This kid is crazy, he even said that the university course is easy?"

"666, although they are all from Shuimu University, but... I don't think I'm so arrogant that I don't need a class? This kid is definitely a megalomaniac. 35

"Awesome, he is a ruthless man who directly contradicts Professor Cao Dexin!

"Perhaps...he was telling the truth?

"Maybe, as far as I know, Wang Jinqiu was not specially recruited in mathematics. He scored 728 points in the college entrance examination, which is really good, but... he can't be so crazy."

""

In the classroom, the students of the mathematics department had a lot of discussion.

They are all students of Shuimu University, and they are all academic masters in various regions, but... even so, they felt that the boy at the door was too arrogant.

After all, this is college, not high school.

Wang Jinqiu also knew that what he said was somewhat inappropriate, but...he really did not intend to contradict Professor Cao Dexin on the stage.

The professor lets himself tell the truth, and what he says is the truth.

For the mathematics course at the university, he had already finished his studies at Gu Bai, and he continued to listen to the professor in the classroom, but it was a waste of time.

on stage.

Professor Cao Dexin put the cup on the podium, and there was no change in expression on his face, but... his eyes did not leave Wang Jinqiu at the door.

After a pause, he said in a cold voice: "What a waste of time, I haven't seen such a frenzied student for a long time."

In Shuimu University, there are not many talented students to talk about, and there are also many students who are proud of themselves.

But...be proud of yourself and have capital, it doesn't mean that once you get admitted to Shuimu University, you won't be able to take classes. The university is not as simple as imagined.

"come over.

After taking a photo of the desktop, Professor Cao Dexin took out a test question from the folder. He looked at Wang Jinqiu, who came over, and asked lightly, "Do you think it is a waste of time to come to the classroom to listen to the class?

Professor Cao Dexin's voice was not loud, but... everyone could feel that Professor Cao Dexin on the stage was angry.

"Apologize and admit your mistake, I feel it's still too late."

"Yeah, Jin Qiu... Don't say anything arrogant, although... I know you are very powerful, but... isn't it appropriate for the professor to subdue you?

"Brother Qiu, shall we keep a low profile.||?"

Several of Wang Jinqiu's roommates looked at Wang Jinqiu on the stage unmoved, and prayed softly, hoping that he on the stage could take the initiative to surrender.

When he walked half a meter to Professor Cao Dexin's side, Wang Jinqiu stopped. Of course he knew that Professor Cao Dexin, who was standing in front of him, was on the verge of breaking out.

But... Wang Jinqiu himself felt wronged, and what he said was the truth.

After a pause, Wang Jinqiu said sincerely: "I am very sorry for skipping class, and I am here to apologize to you.

Hearing the student's apology, Professor Cao Dexin breathed a sigh of relief.

However.

Wang Jinqiu's next sentence really made Professor Cao Dexin's blood pressure rise again.

"But... what I just said was the truth. 35

"I have finished all the courses in the university, advanced algebra, analytic geometry, probability theory and data statistics, differential geometry...em... It seems that there are also topology and Fourier coefficients, so... I think It's a waste of time to continue listening.

Wang Jinqiu clasped his fingers nervously and unconsciously.

But... he felt he had to explain clearly that he really didn't skip class for no reason.

The first few he said were the university courses taught by Gu Bai, and the latter ones were his initiative to ask Gu Bai's mathematical research methods beyond university courses.

"Huh~"

Hearing Wang Jinqiu's words, Professor Cao Dexin on the stage snorted and shook his head.

Arrogant, the students in front of me are really too arrogant.

If he said that he had studied advanced mathematics, analytic geometry and other conventional mathematics subjects, he could still reluctantly believe it.

But when Wang Jinqiu mentioned the methods of topology and Fourier coefficient, Professor Cao Dexin was completely disappointed.

This student is not only arrogant, but... also a liar.

Because the mathematical methods of topology and Fourier are the methods that undergraduates are basically exposed to, unless students study independently and check the materials to learn.

But... is it possible for a student who has just entered the freshman year for one month to master it?

And....how difficult is this extended mathematical tool? As a professor of mathematics, he can't know.

"Does it mean that in your eyes, when you look at the name of the book and flick through some books and materials, it means that you are studying?"

Staring at Wang Jinqiu, Professor Cao Dexin's words were filled with a hint of coldness.

"This...."

Biting his head, Wang Jinqiu said, "I really have mastered these mathematical knowledge points. 95

"Okay, okay, okay." Cao Dexin shouted 3 times in a row, but this was not a compliment, but an angry laugh.

He hated two kinds of students in his life, one is blind and arrogant, and the other is lying.

At this time, in his eyes, Wang Jinqiu had all the two.

"Even though...you said you have mastered it, then...I will see how you have mastered it today.

Saying that, Professor Cao Dexin walked directly to the blackboard.

Write down a few lines of mathematical formulas.

"This... can you understand?"

Wang Jinqiu, who looked at the blackboard, nodded and replied, "Yes.

"what about this?"

"Yes. 39

"Then... how about this?

"Also.

"Really?" 5

Squinting, Cao Dexin turned his head and wrote a topic on the blackboard.

With a smile at the corner of his mouth, he handed the chalk to Wang Jinqiu and said, "Come on...even if you can understand it, solve this Fourier coefficient conversion problem for me."

"`" Good..." Wang Jinqiu took the chalk with a frown and walked to the blackboard.

What Professor Cao Dexin wrote is not an ordinary topic, but... "Discrete Time Domain Fourier Transform of Non-periodic Discrete Signals" in Fourier Coefficients.

As for the Fourier coefficient, Wang Jinqiu asked Gu Bai alone, and Gu Bai also talked about it, but...because it involves non-undergraduate knowledge, Gu Bai did not extend much to him.

"...The Fourier transform can also be written in angular frequency form: ??=2w? whose units are radians per second. Applying ?=??(2) to the above formula, ?(w)=|Rn|f( x)e..."

Recalling the main points and deduction elements of Fourier coefficients taught by Gu Bai, Wang Jinqiu wrote on the blackboard.

The students in the mathematics department under the stage were planning to watch a good show, or they were thinking about the scene in which Wang Jinqiu was 'frustrated' by Professor Cao Dexin.

But... that scene didn't show up.

On the contrary... when everyone's eyes watched the lines of mathematical formulas appearing on the blackboard, they couldn't help but widen their eyes and looked confused.

This.....

What did this special meow write (by Wang Zhao)?

Why... all the characters are familiar, but I can't read them together?

It is confirmed that this is a freshman class, and it is confirmed that Wang Jinqiu on the stage is Te Miao's freshman.

In an instant, the students of the Department of Mathematics of Shuimu University developed various complex emotions in their hearts.

As for Professor Cao Dexin, who was standing beside him, his eyes had long been narrowed into a line.

He picked up the cup on the podium, took a sip of tea, and continued to watch the problem-solving process written by Wang Jinqiu, feeling more and more surprised in his heart.

With the emergence of line by line mathematical formulas, Professor Cao Dexin's surprise gradually turned into shock.

Shouldn't this kid really solve this problem?

This topic was chosen by him from the Yau Chengtong College Student Mathematics Competition. It was the most difficult final question. Few college students across the country could write it, but... at this time, it was unexpectedly chosen by a freshman who had just entered school for less than a month. Broken???

Impossible, absolutely impossible.

How can a freshman, a student who just graduated from high school, have such a high level team.
