Classes, problems, cafeteria, apartment.

Xu Feng's life has returned to its former regularity.

The difference is that Xu Feng and Ye Zhen are going to have a math competition, which has spread all over the campus forum.

Previously, many students questioned Xu Feng's qualifications on the forum.

After all, people who haven't studied for five months.

It's hard to be convinced.

As a result, only a day has passed, and the math competition between Xu Feng and Ye Zhen broke out.

Ye Zhen, a sophomore, is known as the prince of mathematics at Tunghai University.

Every quiz is a perfect score.

Emperor Ge Jun issued a full score in the college entrance examination mathematics test paper.

When I was in high school, I represented my school in various math Olympiad competitions, and I don't know how many I got the first place.

It is even rumored that Ye Zhen completed all four years of mathematics courses in the first semester of his freshman year.

And I'm learning more advanced math.

As for Xu Feng.

If you compete, you may be the first among all students.

But mathematics, except for knowing that he scored full marks in mathematics in the college entrance examination, there is nothing else.

To compete with Ye Zhen like this, it is really self-defeating.

"Ye Zhen is here!"

Before the advanced mathematics class, Ye Zhen came to the classroom where Xu Feng was.

"The competition is scheduled for tomorrow afternoon at 1 p.m., Class 101, Block A, Complex Building. The rule is that you and I will use the content of the first and second volumes of advanced mathematics as the basis, and give each other ten problems on the spot, and the problems must be solved by ourselves. ”

"Yes!"

Xu Feng nodded.

Ye Zhen left, and the students of the first class of genetic engineering looked at Xu Feng one by one.

I really want to have a math competition with the prince of mathematics, Ye Zhen.

And it's also in the case of asking each other's questions.

It's just going against the sky.

You know, many of them can't even write a few formulas.

The campus forum, the math competition about Xu Feng and Ye Zhen began to become the hottest topic.

"Although I don't know how Xu Feng got the qualification, if you want to compete with Ye Zhen, Xu Feng will definitely lose. ”

"Not necessarily, after all, both of them are people who can get a perfect score under Emperor Ge Jun, and it is difficult for millions of college entrance examination students in the entire Jiangdong Province to get a perfect score in mathematics in the college entrance examination. ”

"Stop, don't forget that Emperor Ge Jun said that his college entrance examination papers are actually very simple. ”

"Don't say it, my heart hurts, anyway, they have a live broadcast of the competition. ”

"Well, it depends on tomorrow. ”

......

Back to the apartment dormitory.

Zhuge Xun, Di Yuanshuo, and Mi Gang quickly surrounded him.

"Boss, when did you go out?" asked Zhuge Xun.

"Based on my speculation, the boss must have something urgent to deal with. Di Yuanshuo glanced at the balcony, "Otherwise, I wouldn't have walked from the balcony." ”

"Well, something happened yesterday. Xu Feng said.

"The boss won't go online today, and he organized a group of people with three layers inside and three layers outside, and surrounded the battlefield last night. Zhuge Xun reminded.

"It's not going to be online for a few days. ”

"Boss, do you really want to compare math with Ye Zhen?"

Mi Gang interjected, he and Ye Zhen are in the same department, and he has heard many of Ye Zhen's achievements in mathematics competitions.

"Tomorrow at one o'clock in the afternoon, 101, Block A, Complex Building, you can come. ”

"Skipping class will come too!"

......

One o'clock in the afternoon the next day.

Xu Feng underestimated the influence of the Tunghai University Campus Forum.

It's just a math competition, and most of the complex is surrounded by classmates and reporters, and it's crowded.

"There are so many ...... people"

Zhuge Xun muttered, and Di Yuanshuo and Mi Gang temporarily acted as security guards to escort Xu Feng to Classroom 101 of Block A.

Along the way, reporters from local media in Tokai City took photos from time to time.

From time to time, a reporter came over and asked a few questions.

But apparently now is not the time to be interviewed.

From time to time, cheers, ridicule, and doubts erupted from the crowd.

Xu Feng smiled, ignored the voices of the crowd, and walked into classroom 101 of Block A.

In the classroom, two math professors are sitting and chatting, and there are five student council members who are in charge of live-streaming the competition.

Ye Zhen wore a plaid shirt and sat upright in the middle seat.

On the table is a stack of A4 paper, stationery, and a small calculator.

The clock on the blackboard points to one o'clock sharp.

"You were punctual. Ye Zhen said.

"You're ahead of schedule. Xu Feng smiled.

"Reiterate the rules: based on the content of the first and second volumes of advanced mathematics, ten questions will be given to the other party on the spot, and the questions must be solved by themselves, and the time for solving the questions will be 30 minutes, and the answering time will be 2 hours. ”

"Yes!"

"It's troublesome for the two professors to do notarization!"

Ye Zhen saluted the two professors.

"It's not a hassle, it's fun. ”

"We look at the time, you start. ”

The two professors watched with interest as Xu Feng and Ye Zhen each took out a pen and paper and began to write questions.

The students and reporters who were watching from the windows outside the classroom all quieted down.

The students in the student council immediately focused on the camera.

It's game on!

The speed of the leaf pillow is very fast.

Ten puzzles in ten minutes.

It's a math competition, and he won't keep his hand.

Each question requires at least 100 steps, using a variety of axioms and inferences to solve it.

None of these questions are detached from the content of the first and second volumes of Advanced Mathematics.

In terms of difficulty compared to international competitions.

There won't be much difference.

"Xu Feng, look at how much ability you have!"

Ye Zhen raised his head.

Xu Feng was looking at Ye Zhen with a smile.

If you ask a question or something, it will be solved in three minutes.

"Xu Feng, are you ready? If you don't have enough time, I can give you a little relaxation. ”

Ye Zhen is full of confidence.

The student council classmates in charge of the live broadcast were a little embarrassed.

Xu Feng only took three minutes to figure out the question, and Ye Zhen didn't know it.

"No, let's start exchanging answers. ”

The good questions are handed to the leaf pillow by the professor.

Ye Zhen's heart sank, and he handed over the topic to the professor and transferred it to Xu Feng.

At the same time, the questions from Xu Feng and Ye Zhen were transferred to the audience through the live broadcast.

"Damn, is it the same as what we read?"

"The median value theorem and Lopida's law are enough for people, and this problem from Ye Zhen also needs to use implicit functions, Fourier series, etc., amazing, too powerful. ”

"Don't say it, if you don't say it, we're still friends, I've failed six times in high math......"

"Look, they're going to start answering questions!"

Question 1.

Decent way.

Is it the humility of the leaf pillow?

Xu Feng looked at the second question and was in good spirits!

This problem is almost a synthesis of most of the content of the first book of advanced mathematics, and the solver needs to bypass the long math maze to get the answer.

It is worthy of being called the prince of mathematics!

Xu Feng's first question was not too difficult.

Ye Zhen solved it easily, and his heart was relieved, but the problem was nothing more than that.

When I saw the second question, I was shocked: "This question actually asked me to use Fourier series to solve it, and there are many traps." No, using the Fourier series is a complete trap!"

Ye Zhen thought for thirty seconds and began to answer the question: "Xu Feng, this question is still difficult for me!"

Audience A: Are these two still human?

Audience B: The topic is so difficult, but it can still be done.

Audience C: Have you noticed that Xu Feng's speed of doing questions is accelerating?

"That's what I want, yes!"

During his studies in advanced mathematics, Xu Feng did many problems, and only the current problems could make him feel excited.

Correspondingly, Ye Zhen got stuck when he did the third question.

The pen is a hedgehog.

Can't start......

Is this really a question made by normal people?!
