The finale of last year's college math contest finals?

Cheng Nuo was taken aback.

Although I had expected the origin of this set of questions, I didn't expect it to be last year's competition topic.

It is also a competition topic for third- and fourth-year mathematics majors.

No wonder it's so difficult.

You must know that Cheng Nuo is only a freshman who has been enrolled for more than a month.

In last year's competition finals, there must have been their Tsinghua seniors participating.

In other words, even the seniors who have studied in the mathematics department of Tsinghua University for three or four years have not been able to completely solve the last three problems.

Thinking about it like this, Cheng Nuo's heart felt better.

"Alright, show me your steps. Professor Lu said to Cheng Nuo, "I said before that you should choose one of the three questions to do. ”

"But if you don't do it right, I won't sign it. ”

Cheng Nuo nodded, "Well, teacher, I know." ”

"Oh, you're so confident?" Professor Lu said with a smile as he took Promise's answer. "Then I'm going to see how good you are. ”

Professor Lu is not familiar with Cheng Nuo.

In other words, until now, Professor Lu did not know the name of the student standing in front of him.

The purpose of giving Cheng Nuo the three finale questions in the finals of last year's competition was to make the student in front of him retreat.

Let him know that it is almost impossible to get the exemption qualification of his course!

Can ...... now

After just over ten minutes, the student told him that he had solved a problem.

This really surprised Professor Lu.

and the momentum on Cheng Nuo's body, which does not look like he has no confidence at all.

Professor Lu had to take it seriously.

This student ...... It seems that he still has real skills!

Thinking like this in his heart, Professor Lu took the page full of formula answers written by Cheng Nuo in front of him and read them line by line.

In the entire office, only the gasps of two people remained.

Cheng Nuo stood aside, looking at Professor Lu who was checking his answers, and his heart was unwavering.

Cheng Nuo is 100% confident in his own proof steps.

Cheng Nuo either can't do any math problem, but if he does, he will definitely be able to do it right!

With Rejoice, drink Kidney Treasure, it's so confident!!

Professor Lo was quick to browble, and he already had the answers in his head, plus a strong sensitivity to those mathematical formulas.

In less than two minutes, without taking a pen to calculate on scratch paper, Professor Lu had already read all the proof steps of the third question given by Cheng Nuo, one page, and a total of more than 20 formulas.

Professor Lu slowly put down the A4 paper in his hand, raised his head, and did not speak, just stared at Cheng Nuo.

Silent......

Long silence......

Silence is Cambridge tonight.

After being stared at by Professor Lu for two or three minutes, Cheng Nuo was now panicked.

Professor Lu, he won't ...... Covet my handsomeness, right?

"Teacher, my question ......" Cheng Nuo couldn't stand this strange atmosphere, scratched his head, and said with a sneer.

Professor Lu still didn't speak, but just took Cheng Nuo's application form in front of him, and signed his name in the blank space signed by the teacher.

"Take it!" Professor Lu pushed the completed application form in front of Cheng Nuo.

"Thank you, teacher. ”

It's finally here!

Cheng Nuo was extremely excited, picked up the application form, turned around and was about to leave.

"Wait a minute. ”

At this time, Professor Lu's voice came from behind Cheng Nuo.

Cheng Nuo's figure suddenly froze.

He turned around reluctantly, and the corners of his mouth barely pulled a smile, "Teacher, is there anything else?"

"Are you interested in participating in next year's math competition?" Professor Lu said unhurriedly.

............

"The ——! is finally over. ”

Walking out of Professor Lu's office, Cheng Nuo exhaled.

He raised his wrist and looked at the time. It was already past five o'clock in the afternoon.

Cheng Nuo spent more than half an hour in Professor Lu's office.

Regarding Professor Lu's suggestion that Cheng Nuo should participate in next year's college student mathematics competition, Cheng Nuo has not given an accurate answer.

Anyway, the annual college student math competition is held at the end of March.

It's still early, and even the registration won't start until the end of the semester, so there's no hurry.

In fact, deep down, Cheng Nuo is not excluded from participating in next year's mathematics competition.

While you are young and only a freshman, you should brush up on domestic awards first and exercise your competitive ability. Prepare for the international pretense in the future.

By the time of the junior and senior years, a domestic math competition may not be able to match Cheng Nuo's forced qualification.

Can be critical ......

I heard that students who sign up for the math competition will stay in school for a period of time during the winter vacation to receive training.

It's the winter vacation again!

Cheng Nuo is very sore now.

When I was in high school, the winter and summer vacations were hard enough! I finally got through to college, only to find that in college, it was not so easy to have a good winter vacation!

We'll talk about it later!

Whether to participate in next year's digital competition, Cheng Nuo can only discuss it later.

............

Saturday, 9:50 a.m.

Cheng Nuo and Maddie came to the tennis court next to the school's east playground together.

Today, it is the tennis team that conducts the selection of players.

According to Maddie to Cheng Nuo, the tennis team consists of a total of ten players.

Seven full-time players, three substitutes.

All of the participants are freshmen and sophomores, and there is at least one student from each class.

And Cheng Nuo is the representative of the Department of Finance in 2020.

When Cheng Nuo and Maddie arrived on the playground, everyone had already arrived.

Cheng Nuo glanced at it.

A total of 20 students participated in the selection, all of whom were boys.

Twenty out of ten, even if it is a few blind choices, Cheng Nuo has a 50% chance of being selected, and the probability is still quite large.

And the quality of the contestants participating in the selection is naturally uneven.

Even, Cheng Nuo also saw a boy with a plump physique than a little fat man, who obviously came to make up the numbers.

After all, it's the tennis team that has to be selected. It is a fairly unpopular ball game among students.

If you want to select a tennis team, table tennis team or something, there are definitely more than enough students who sign up.

Especially the table tennis team, which is a level that a school team can abuse foreign professional players.

"Okay, everyone is here, I won't delay everyone's time, hurry up and finish the selection, and then we will start the training of the academy team. "The minister of the sports department of the college association who is in charge of the selection of the college team, a tall junior sister with healthy wheat skin.

Cheng Nuo knew her name from Maddie, He Ruge.

He Ruge stood in front of everyone and explained the selection rules, "The selection rules are also very simple, I will randomly divide you into ten groups." Ten goals, whoever scores more points will enter the house team. ”

The rules are simple and straightforward, and again, there is a lot of chance and uncertainty.

However, it's just a simple selection of the academy team, and the players are all lacking in interest, just formalize it.

As for the winning ...... It's completely casual.

In the draw, Cheng Nuo drew five groups, and the opponent was a boy with glasses.

There are two courts in the volleyball court.

Soon, it was Cheng Nuo's turn to play.

"Cheng Nuo, come on!" Maddie acted as Cheng Nuo's only cheerleader.

Cheng Nuo waved the tennis racket to indicate ojbk!

The first ball, Cheng Nuo serves.

On the other side of the net, the boy with glasses bent down and held a tennis racket, waiting for him.

"Hey, buddy, you've heard of it...... Didn't have an outspin serve?" Cheng Nuo shouted to his opponent in the air. "Be careful!"

At the same time, Cheng Nuo threw the tennis ball high!
