The college student was stunned for a while, then said with difficulty: "Yes, you are awesome, I'm convinced."

Dozens of replies popped up in the comment area:

"Amazing, he answered almost instantly, and he came up with four proofs in such a short time, all of which were correct. I finally understand why the organizing committee of the National Mathematical Olympiad gave him a miracle score of 1 point! Qin Shen,

I will call you that from now on! You are such a god!"

"I searched specifically and found that there is no such question on the Internet. I don't know which tutorial book the classmate just found it from. The possibility of Qin Ke cheating is very low."

"It's impossible to cheat, okay. I can testify with my classmates that the question just now was chosen by more than a dozen of us! We are convinced. This time we are really convinced! Qin Shen, who will question it in the future?

You, we will jump out to help you testify!"

A few more college-looking boys sent in messages and asked questions about probability theory and geometry. Qin Ke also answered them instantly.

One time it might be a coincidence, the other time it might be a fluke, but seven or eight times in a row, those who questioned and said weird things in the comment area finally became less and less, replaced by a series of shocks and exclamations.

The ninth person to win was a boy with a thin face and thick black-rimmed glasses.

"Hello, Qin Ke, my name is Zhang Xiangdong, and I am currently a senior undergraduate majoring in mathematics at Tongqi University. Based on your paper, I judge that your calculus level is very high. I happen to have an academic question that I would like to discuss with you.

You communicate."

Someone in the comment area quickly started writing in shock: "Zhang Xiangdong! He is Zhang Xiangdong! Zhang Xiangdong won two individual gold medals, the Grandmaster Hua Award and the Grandmaster Zhou Award in last year's Grandmaster Qiu College Mathematics Competition!"

"What are the 'Grandmaster Hua Award' and 'Grandmaster Zhou Award' upstairs? Please explain! Those who are not majoring in mathematics will not understand."

"The 'Grandmaster Qiu College Mathematics Competition' has several competitions in different directions. The 'Grandmaster Hua Award' gold medal is in the direction of analysis and differential equations, and the 'Grandmaster Zhou Award' is in the direction of algebra, number theory and combination. Both are individual projects.

The gold medal, only ten college students in the country can win this honor!"

“Hiss—the master of mathematics!”

"Amazing, this is a real master of mathematics!"

"Yes, Zhang Xiangdong is very famous in the mathematics circle of our university!"

"This time the real academic god from the university is here. I'm inexplicably worried for Qin Ke."

"Zhang Xueshen, please be patient with your questions and don't be too professional. Qin Ke is self-taught, not a super academic like you who studied with your tutor for four years in university..."

Zhang Xiangdong ignored the comments and asked directly: "There are two discretization methods for the fractional calculus operator S^(/-r), direct discretization and indirect discretization. The indirect discretization method needs to be compared with the frequency in the continuous time domain first.

Domain matches..."

After uttering a series of dizzying sentences, he continued:

"The research I am currently doing is based on the basic algorithm of rational Chebyshev approximation and the direct approximation method of the fractional-order operator of rational Chebyshev approximation to study the optimal approximation of rational approximation. My question is

:If three operators, euler, Tustin and Al-alaoui, are used to generate functions, which one has better approximation properties?"

The comment area fell into silence again. Most people in the small auditorium, including many math teachers, had their eyes wide open and looked confused.

",It's like listening to a book from heaven!"

"I don't understand it at all. Is this the world of the god of learning?"

"Don't let mortals get close! It's so terrifying!"

"Zhang Xueshen is too cruel...I am also a senior majoring in mathematics, so I said I didn't understand."

“I studied in the first year and didn’t understand it. I only knew that it was a discretization problem of fractional calculus operators, but the question was too detailed and in-depth... I couldn’t answer it at all, and I was afraid that no one in our school could answer it.

"

Hearing that the question this time was particularly difficult, Ning Qingyun next to him also looked at Qin Ke nervously, only to see Qin Ke smile slightly: "Brother Zhang, you are cheating a bit. Although it is an academic discussion, it all involves yours."

The thesis is in a field of study, but the knowledge points are still so unfamiliar... If I hadn't just learned about Chebyshev polynomials, I would have been asked questions here today."

Zhang Xiangdong's eyes flashed with strange color, and he asked with interest: "Can you answer?"

"My answer is that the fractional-order integral operator S can be expanded through the CFE and RCA methods, and the approximation characteristics can be compared from both the time domain characteristics and the frequency domain characteristics..."

Qin Ke wrote as he spoke, writing several extremely complex function expressions on the white paper on the table.

The camera zoomed in in time and focused on the white paper. Everyone: "..."

Can anyone tell me what the hell this is about?

It was as complex as a magic spell, making people dizzy just looking at it. The daunting mathematical symbols made more than 90% of the people watching the live broadcast gasp.

In particular, many anchors who took advantage of the popularity to provide live broadcast commentary collectively lost their voices and could not continue talking at all!

This is no longer an advanced field that ordinary mathematics undergraduates can access.

"At this point in writing, Brother Zhang, I shouldn't need to tell you the answer, right?" Qin Ke wrote very quickly and put down the pen in less than three minutes.

Zhang Xiangdong was silent for a moment while watching the writing process, and finally said: "I admire it, it's amazing. It has given me a lot of inspiration. If I have any questions in the future, I will ask you again."

Qin Ke smiled, cupped his fists and said, "I have also benefited a lot. Please contact me more when I have time."

Everyone: "..."

What's the matter with your expressions of sympathy after a competition between super masters? Can you give me an explanation?

"Damn it, now I really hate myself for not studying hard. I looked so lonely and couldn't say anything except 'f*ck'."

"They were speaking Mandarin just now, right? How come I understand every word, and when you put them together... what the hell is this?"

"Excuse me, I don't deserve to watch this live broadcast. I'm going to roll. Automatic roll, 360-degree rotation roll."

"I feel like if I continue watching this live broadcast, I will feel like a retard. Farewell!"

"I can't even understand what I'm hearing. I don't even know what's wrong with Qin Ke. Is this the terrifying thing about the god of learning?"

"In the past, when I used to criticize people in the live broadcast room, I always said, 'Have you got a brain? You can even say such a thing?' Now I have to seriously think about whether I have a brain..."

"Let me tell you a secret. As long as you pretend that you understand it, you will suddenly feel that you are superior to others."

In addition to 6666 comments in the comment area, there is a series of self-deprecating comments that make people laugh and cry.

Qin Ke put down his pen, rubbed his wrist, and asked: "Do you have any more questions to ask? It's only been fifty minutes, and there's still more than an hour left. Come on, come on, I just got excited about chatting, let's do something like this

The academic questions that Senior Brother Zhang just asked were difficult or more difficult."

It was actually quiet for a while this time, and no one even connected.

"Boss, I suggest you take a sip of tea and rest for a while. Your attack power is too strong. It may take time for the enemy to prepare artillery fire..."

"That's right... I'm too embarrassed to ask the 'hard questions' I prepared, for fear of being regarded as mentally retarded."

"The topic is too high-end and I can't afford it, so I'll just take a look and won't ask any questions."

"Qin Shen is so powerful. You showed me what it means to be truly powerful in the world. It's even more exaggerated than online novels!"

"Oh, you guys are so considerate, so I won't ask any questions for now. I'll drink tea first." Qin Ke took the tea from Ning Qingyun and drank it calmly.

"Hey, will the tea brought by classmate Ning be more fragrant and delicious, Qin Shen?"

"It tastes good, but the black tea has been brewed for a little too long, so the tea tastes a bit harsh."

"Qin Shen, do you still know about tea ceremony?"

"I understand a little bit..."

"Hey, have you noticed that the building is completely crooked? Isn't this the live broadcast of Qin Shen's academic exchange on mathematics?"

Seeing this scene, all the principals and teachers of Yingyuan High School in the audience laughed. The big stone hanging in their hearts finally let go, and they were replaced by full of shock and surprise!

This Qin Ke has really created too many miracles for them!

It’s a sure win this time. Principal Wen’s bet is a sure win!

The students in the audience are all eyes full of little stars. Oh my god, Brother Ke has single-handedly challenged college students across the country, and now no one dares to ask questions! For fear that the questions are too simple and they will be ridiculed!

Brother Ke is too powerful, isn't he?
