Chapter 99 Ask for a recommendation ticket
"scare!"

Fang Chao turned around, startled.

"Teacher, why are you scolding me behind my back?"

"I didn't scold you, you do your problem, what do I do."

This tutor regretted it very much. He lost his image, and he actually swears in front of the candidates. This is very unlike him.

"Oh."

Fang Chao responded, and didn't bother with the teacher anymore, but continued his answer.

In fact, this question can be solved with another way of thinking. Anyway, there is still a lot of time, and the third question is not in a hurry, so he wrote down the second problem-solving steps in the blank space. The picture can express the problem-solving ideas more clearly at once.

Let a1=a+b, a2=c+d, a3=c+a, a4=b+c, ​​a5=d+c
……

……

The maximum value is 288, when a, b, c, d, e are -1, -1, -1, 4, 4 in sequence.

The minimum value is -512, when a, b, c, d, e are -1, -1, -1, -1, 9 in sequence.

"Perfect."

"To put it simply, there are two ways to solve the problem. I don't know if they can get me a little more points..."

Fang Chao solved the second question. The first idea took about 10 minutes, but the second idea only took about 10 minutes. The second question took a total of half an hour to solve the two ideas A little more time.

It's not that the second problem-solving idea is faster to calculate.

In fact, it is far more complicated than the first way of solving problems, and its calculation steps and algorithms are also more, but it presents the answer most intuitively, so that anyone can easily understand it, not necessarily You need to be a master to get it done.

It's just because Fang Chao has already understood this question and understood its problem, so he can list the answer in 10 minutes.

"Teacher, why are you still behind me... You are affecting my answer... I always feel like there is a pair of eyes staring at me from behind. It's so uncomfortable..."

Fang Chao turned around and found that the previous mentor was standing behind him lingeringly, his eyes had been staring at him and never left. This reminded Fang Chao of his bad past. Heimian Tan leaned against the windows in the back row of the classroom to observe secretly many times, and Fang Chao was secretly caught several times playing games, which caused him a psychological shadow.

Although now he and Heimian Tan have become an inseparable teacher-student relationship, the dark days will not disappear with time. So far, whenever he feels that there are eyes secretly looking at him in the dark, Fang Chao will be all over his body. uncomfortable.

When he was too immersed in the math problem, he didn't realize that after completing the second math problem, Fang Chao felt a creepy feeling that he was not used to.

"I just happened to walk over to you. You can do your questions and don't worry about me. I'll just walk around and leave."

The mentor couldn't admit that he had been standing behind Fang Chao, but he secretly clicked his tongue. There was a dark horse in this year's national finals. An absolutely strong dark horse. Fujian, which has been silent for several years, is about to rise this year. what?

In previous years, when it comes to the CMO national finals, one can imagine how embarrassing Fujian's status is. Apart from high housing prices, it can't even have an advantage over other cities in other aspects, and even in In terms of education, above the national finals, in the past six to seven years, not to mention the awards in the individual competitions, even the awards in the team competitions have not been seen in Fujian.

The boy in front of him is only a freshman in high school, but from the first question to the second question, the total time for the two questions is less than one and a half hours.

Four and a half hours to go, with three hours left to go, something that would have been almost unimaginable in the past.

Are the test questions too easy?Only then can people solve two questions in such a short period of time.

No, not really...

Up to now, there are many candidates who are still stuck in the first question.

Are these people stupid?
They are not stupid at all. They are all provincial mathematics geniuses selected from thousands of provinces. Even they are still stuck on the first question of CMO, which naturally shows the difficulty of the national finals.

But this kid is really good at pretending...

The instructor was thinking this, but he soon felt relieved. Geniuses all have some quirks, which is easy to understand.

Mathematics genius, what is pretending to be?Is mathematics without pretense still mathematics?How can ordinary people understand the charm of mathematics? Falling in love in mathematics is the most wonderful thing in life, isn't it?It was because of his high level of mathematics that he met a Chinese student who was studying abroad at the lakeside of the Seine. His wife was seven years younger than him. The two are currently happily married and have two children. Daughter, how can people who don't understand mathematics know the beauty of life?
At this moment, Fang Chao's eyes were set on the last question of the CMO National Finals.

As the last question on the first day of the National Judgment, like in previous years, he used the geometry question as the finale. This is a question that really tests students' computing ability, logical ability, and thinking ability, and this question is also used to really increase the score. of a question.

Fang Chao was not in a hurry to solve the questions, but started to review the questions first. Geometry questions are the most despicable. The auxiliary lines come out one by one, and each auxiliary line is your lifeblood. You need to complete the answers you need on these auxiliary lines. The number of auxiliary lines is up to you. The questions are given by others. The right to decide the difficulty level of the game.

But the GM is too despicable. He has an excellent foundation in mathematics. His foray into mathematics started even when you were a tadpole.

He is not necessarily a dead end, but any error in the line may delay time.

The game is set up with a set time.

That is hours.

Once you can't find a way out within the specified time, then you will be declared GAME OVER, and the CD cooldown will be one year. See you next year at the CMO National Finals.

I love you so much, let’s meet in the world.

A mistake in one line may delay half an hour or even an hour, or it may be that your line is wrong from the very beginning...

Facing the geometry problem, even Fang Chao did not dare to be careless.

The instructor not far away continued to observe secretly. Did this third question trap him?Sure enough, it's not omnipotent.

After about 15 minutes, Fang Chao took out his 2B pencil and began to draw two auxiliary lines on the x and y axes respectively on the circumscribed and inscribed circles of the two geometric circles.
