Chapter 259: National College Student Mathematics Competition?

What was the finale topic of last year's mathematics competition for college students?
Cheng Nuo was taken aback.
Although I expected the origin of this set of questions, I didn't expect it to be the question of last year's competition.
And it is also a competition topic for third and fourth grade mathematics students.
No wonder it is so difficult.
You know, Cheng Nuo is only a freshman who has been in school for more than a month.
In the finals of last year's competition, their Tsinghua seniors must have participated.
In other words, even the seniors who have studied for three or four years in their Tsinghua Department of Mathematics, no one can completely solve the last three questions.
Thinking this way, Cheng Nuo felt a little better in his heart.
"Okay, show me your problem-solving steps." Professor Lu said to Cheng Nuo, "I said before that you should choose one of the three problems."
"But if you don't get it right, I won't sign this word."
Cheng Nuo nodded, "Well, teacher, I know."
"Oh, are you so confident?" Professor Lu smiled while receiving Cheng Nuo's answer. "Then I have to see how capable you boy is."
Professor Lu is not familiar with Cheng Nuo.
In other words, until now, Professor Lu still doesn't know the name of the student standing in front of him.
Given to Cheng Nuo's three final questions in the final of last year's competition, Professor Lu's purpose is to let the student in front of him retreat.
Let him know that it is almost impossible to get the exemption qualification for his course!
But now...
After only ten minutes, the student told him that he had solved a problem.
This really surprised Professor Lu.
There was also the aura of Cheng Nuo, not at all as if he had no confidence.
Professor Lu had to take it seriously.
This student... seems to have real skills!
With this in mind, Professor Lu took the page-filled formula answer written by Cheng Nuo in front of him, and looked at it line by line.
In the entire office, only two gasps were left.
Cheng Nuo stood by and looked at Professor Lu, who was checking his answer.
Cheng Nuo has 100% absolute confidence in his proof steps.
Cheng Nuo can't do any mathematics problem. If he does, he can do it right!
Using Rejoice and drinking Shenbao is so confident! !
Professor Lu's browsing speed is very fast, he has the answers in his mind long ago, plus his strong sensitivity to those mathematical formulas.
In less than two minutes, without taking a pen to calculate on the draft paper, Professor Lu has read all the more than twenty formulas on one page of the third question given by Cheng Nuo.
Professor Lu slowly put down the a4 paper in his hand, looked up, did not speak, just stared at Cheng Nuo.
silence……
Long silence...
Silence is Cambridge tonight.
After being stared at by Professor Lu for a full two to three minutes, Cheng Nuo was now panicked.
Professor Lu, he won't...covet my handsomeness, right?
"Teacher, this question of mine..." Cheng Nuo couldn't stand this weird atmosphere, scratching his head and chuckling.
Professor Lu still did not speak, but took the application form of Cheng Nuo in front of him, and signed his name in the blank space where the teacher signed.
"Take it!" Professor Lu pushed the completed application form in front of Cheng Nuo.
"Thank you, teacher."
Finally got it!
With excitement in his heart, Cheng Nuo picked up the application form and turned around to leave.
"Wait."
At this time, Professor Lu's voice came from behind Cheng Nuo.
Cheng Nuo's figure suddenly stopped.
He turned around reluctantly, and forced a smile at the corner of his mouth, "Teacher, what else?"
"Next year's math competition, are you interested in participating in it?" Professor Lu said in a hurry.
…………
"Huh! It's finally over."
Walking out of Professor Lu's office, Cheng Nuo exhaled.
He raised his wrist to check the time. It's already over five in the afternoon.
Cheng Nuo spent more than half an hour in Professor Lu's office.
Regarding Professor Lu’s proposal to let Cheng Nuo participate in the math competition for college students next year, Cheng Nuo has not yet given an accurate answer.
Anyway, the annual mathematics competition for college students will only be held at the end of March.
It’s still early, and even the registration will not start until the end of the semester, so don’t worry.
In fact, deep down, Cheng Nuo does not exclude participation in next year's math competition.
Take advantage of the young, freshman year, first brush more domestic awards, exercise your competitive ability. Prepare for the international pretense in the future.
By the time of the third and fourth year, a domestic mathematics competition might not match Cheng Nuo's compulsion.
But the key...
It is said that students who sign up for mathematics competition have to stay in school for a period of time during winter vacation for training.
It's another winter vacation!
Cheng Nuot's is very painful now.
In high school, winter and summer vacations were hard enough! It was hard to get through to university, and then I realized that in university, it is not so easy to think about spending a good winter vacation!
Negotiate later!
Cheng Nuo can only discuss whether to participate in next year's digital competition.
…………
Saturday, 9:50 in the morning.
Cheng Nuo and McGrady came to the tennis court next to the school's east playground.
Today, it is the Academy Tennis Team that selects players.
According to McGrady's disclosure to Cheng Nuo, the tennis team consists of ten players.
Seven official players and three substitutes.
Participating in the selection are all freshmen and sophomores, with at least one student in each class.
And Cheng Nuo is the representative of the 2020 Finance Department.
When Cheng Nuo and McGrady arrived on the playground, they were already there.
Cheng Nuo glanced.
A total of 20 students participated in the selection, all of them were boys.
Twenty to choose ten, even if it is a few blind selections, Cheng Nuo has a 50% chance of being selected. The probability is still quite high~EbookFREE.me~ and the quality of the players participating in the selection is naturally mixed.
Even Cheng Nuo saw a boy who was plumper than a fat man, and he obviously came to make up the count.
After all, it is the tennis team to be selected. It is a very popular ball game among students.
When it comes to selecting a tennis team or table tennis team, the students who sign up are definitely more than that.
Especially the table tennis team, that is the level at which a school team can kill foreign professional players.
"Okay, everyone is here. I will not waste everyone's time. I will finish the election as soon as possible, and then we will start the training of the college team." The director of the college sports department responsible for the selection of the college team, a tall man, Junior sister with healthy wheatish skin.
Cheng Nuo knew her name from McGrady, He Ruge.
He Ruge stood in front of the crowd, explaining the selection rules, "The selection rules are also very simple. I will randomly divide you into ten groups. Ten balls, whoever scores more points, will enter the academy team."
The rules are simple and straightforward. Again, there is great contingency and uncertainty.
However, it was just a simple selection of the academy team, and the players were all lacking in interest, just formalized.
As for winning...it's completely reckless.
In the draw, Cheng Nuo drew five groups. His opponent was a boy with glasses.
The volleyball court has two venues.
Soon, it was Cheng Nuo's turn to play.
"Cheng Nuo, come on!" McGrady stood by as Cheng Nuo's only cheerleader.
Cheng Nuo waved the tennis racket, indicating ojbk!
Cheng Nuo served the first ball.
On the other side of the net, the boy with glasses bowed and held a tennis racket, waiting for him.
"Hey, buddy, have you heard of...external spin serve?" Cheng Nuo shouted to his opponent from the air. "Be careful!"
At the same time, Cheng Nuo tossed the tennis ball high!
