Chapter 148 Are these questions correct?Does it really exist? ? ?

"untie……"

"Synchronize the equation of l with the equation of the ellipse."

"Eliminate y."

"have to……"

“(1？9tan2？)x2？362tan2？？x？72ta？n？9？0？6tan2？？6？ab？？tan？x2？x1？？tan？？？22(1？9tan？)1？9tan？。”

"From ab? 2, get tan?? 213, ???tan??, 333???? 5??, ?? The value range is ? 0, ?????? 6?? 6?. "

"..."

This question is really easy.

As long as you can master the chord length formula proficiently and use it flexibly, you can almost do it with your eyes closed.

Such as Jiangnan.

It took less than half a minute to set up.

then……

It took another 1 minute to double check.

after all……

Don't be afraid of [-], just be afraid of what happens.

Control points 60.

Points will be deducted if there is too much or too little, if you accidentally make a mistake and do not reach 60, then you will be finished.

He was still waiting for the second and third rounds to slap Liu Fan and his group in the face, but he must not capsize in the gutter.

"Humph!"

"Annoyed Lao Tzu again and again."

"If I don't let you know why the flowers are so red."

"Then am I really a Teenage Mutant Ninja Turtle?"

"A bunch of little bastards, just wait!"

"..."

It's worth mentioning.

The Olympiad preliminaries are usually two and a half hours long.

But each round of the rematch is usually three and a half hours.

Although the number of questions is the same, an extra hour is added, obviously the difficulty is greatly increased.

but……

Gangnam is done in less than 10 minutes.

It's even checked out.

Then he got up and handed in the paper.

The Mathematics Olympiad competition is different from ordinary exams. There is no such thing as not being able to hand in papers before the time.

after all……

If not do.

No matter how hard you think about it, you won't do it.

Instead of staying in your seat for a few hours, it is better to give up and leave, which can also relieve the pressure on the invigilator.

of course.

Pay early and leave early.

Although it can relieve the pressure on the invigilator.

But in the eyes of the proctor.

Those who hand in the papers in advance are basically hopeless.

Just like Jiangnan.

Good guy!
Others submit papers in advance.

It's only half an hour, a few hours.

But now, less than 10 minutes after the exam started, Jiangnan handed in the paper.

what is this?
No effort at all, just give up?

It's too unmotivated!

"Student, don't you know how to do a single question? You gave up within 10 minutes of the exam?"

"If you had known this before, you shouldn't have come to take the exam. Not to mention wasting the quota in your city, it would also consume manpower and material resources."

"..."

Jiangnan: "..."

Why do I hand in the paper every time.

The invigilator wants to scold him?
Forget it.

You didn't read my paper, so I don't care about it with you.

"Teacher, I seem to have a bad stomach at noon. I don't feel well. I have to go to the bathroom, so...bye."

Finding an excuse, Jiang Nan just walked away.

but……

That's just fooling around.

In the eyes of the invigilator, Jiang Nan just doesn't have enough strength, he won't be unable to stay on one question, and it's just soy sauce.

Or...

Just want to go to the toilet to smoke.

This……

These are the routines that students are used to.

but……

It is said that Jiangnan is really not playing tricks.

Although he can smoke or something.

But that thing is harmful to health, he had smoked it in his previous life, but he has never even touched it in this life.

At the same time.

The moment Jiangnan left the examination room.

Most of the candidates in the classroom looked up at Jiangnan with a hint of surprise in their eyes.

after all……

Qualified to participate in the Mathematical Olympiad semi-finals.

All of them are top students from all cities in the province.

Everyone has one goal in mind, that is to get a ranking, at least get second place, and get 10 points in the final exam.

and so……

No matter how difficult the topic is.

It's so difficult that they want to cry for their father and mother.

They are also gritted their teeth and persisted.

But Jiangnan handed in the paper within 10 minutes of the exam.

This……

It's really unprecedented, even in the history of Binhai Mathematical Olympiad rematch, it's the first case!

but……

Then they bowed their heads.

Continue to immerse yourself in the nightmare of solving problems.

Jiangnan's submission of papers is Jiangnan's business and has nothing to do with them. It happens that there is one less competitor.

There was only one person who was still staring at Jiangnan Yuanqian's back, and that was Su Yun from Jiangcheng No. [-] Middle School.

Among the candidates from Jiangcheng, he was the only one assigned in the same examination room as Jiangnan.

And before the exam.

He also spoke harshly to Jiangnan in public.

natural!

He paid special attention to Jiangnan.

And leave with Jiangnan handing in the papers.

He had mixed feelings in his heart for a while.

How to say?
Should you be happy?

That's for sure.

After all, Jiangnan is the opponent he wants to beat. Now that Jiangnan abandons the exam and leaves, it is 100% eliminated in the first round, and he will not be able to advance to the second round. Of course he will be happy.

but……

In addition to being happy.

There was also a hint of admiration secretly in his heart.

I admire Jiangnan's courage.

How dare you give up the exam as soon as it starts in the provincial capital, Binhai, under the watchful eyes of so many people?
In fact...

He also had a thought of giving up the exam.

just because...

This paper is really too difficult.

Nima!

It's against the sky!
As early as when he got the paper, the first moment he opened it, the first time he saw it, he felt something was wrong.

"Set a={x|x+x-6=0}, b={x|ax+1=0}, if b? a, then a=___2."

This is the first question.

But why can't he understand it?

Thinking for a long time.

He couldn't start, so he had to jump over.

He understood the second question.

"50 students have done physics and chemistry... If it is known... then there are __ people who have done both experiments correctly."

This is a cubic equation solving problem.

It is not difficult to understand.

But it is not easy to do it.

He tried his best and racked his brains to solve the answer with difficulty, but he hadn't had time to be happy.

When he saw the third question.

"The set a??x|x??3 or x?3?, b??x|x?1 or x?4?, then a?b?___."

Su Yun: "????"

What?

What the hell is this?

Not right, so wrong.

In other words, he had never encountered such a problem before.

There is no solution at all!
Skip again.

Then look at the fourth question, the fifth question, the sixth question...

Ok!

One is more difficult than the other, not to mention the idea of ​​solving the problem, he can't even understand the problem, and he wants to vomit blood.

for a while.

He fell into the deepest doubts.

"Are these questions correct?"

"Do these issues really exist?

"Is there really someone who can do such a topic?"

"..."

After all, he is also a top student, No. 1 in Jiangcheng No. [-] Middle School.

In the entire Jiangcheng, although the ranking is a little lower than that of No. [-] Middle School Liu Fan, No. [-] Middle School Du Jiang, Chuying Xiaji and Lanpu Mengchuan.

but……

He is also confident that he can compete with those people.

But now...

Look at this paper.

He has the feeling of a primary school student reading a high school question.

Just reading the bible.

Confused.

Really.

He's about to take the autism test.

Is this Mathematical Olympiad rematch paper so difficult?

The preliminaries in the city were already difficult enough. He usually scored full marks in mathematics, but last time he only scored more than 70 in the test.

but now……

Compare with this rematch paper.

The papers for the preliminary round are so easy!
Not at the same level at all.

He's going to be tortured insane.

Almost subconsciously.

The idea of ​​giving up the exam came to his mind.

One paper, only one question is done, and the rest can't be done, so what else can I do if I don't give up the exam?
but……

He immediately suppressed the thought.

It is not possible to give up the exam.

He doesn't have the courage of Jiangnan.

after all……

So many people watched.

They are all academic masters, and he also needs face.

And he still bears the hope of No. [-] Middle School. If he gives up the exam, how will he explain to the teacher and the school?

"Jiangnan, Jiangnan."

"You dare to give up the exam, I admire you very much."

"But I will never give up the exam no matter what. Even if I can't do it, I will persist until the end."

"There are still more than three hours. Persistence is victory. Even if I am eliminated in the first round, I can at least beat you."

"..."
