Chapter 440: Math League

Qin Fei got out of the car with Liao Yanmei's help.

After stepping on the earth.

Qin Fei didn't have much of a problem anymore.

Teacher Mediterranean gathered everyone together and gave a brief explanation.

"Everyone bring all the exam supplies, as well as the admission ticket, hurry up and follow the guidance of the map to find the exam room where they are, there are ten minutes to take the exam, after the exam, everyone comes out here to gather, and then eats together and then goes back." ”

Everyone was a little panicked when they heard it for ten minutes, after all, they hadn't stepped on the scene.

Everyone is unfamiliar with life.

I don't know if I can find the exam room smoothly.

"What if the teacher can't find the exam room?" said one student, who estimated that he was usually pampered.

"If you're such a big person, you can't find an exam room for ten minutes, and you don't need to take the exam, just come back, it's useless to let you take the exam. ”

Mediterranean is not that kind of mother-in-law teacher.

A sentence went back.

Sure enough, he has a lot of character.

Qin Fei liked it very much.

So everyone stopped talking nonsense.

Asking is also a waste of time.

Spread out separately.

Find your own testing room.

Qin Fei saw Liao Yanmei standing still.

The expression was anxious.

I want to ask people but don't dare.

Look at the map for yourself and look at the objects around you.

I'm about to cry.

It seems that there is no direction in any direction.

It's the same as Cao Ying.

I don't know if Cao Ban has arrived in the provincial capital.

.....

"What time is your exam room? ”

Qin Fei thought for a moment, walked over and asked her,

"I'm number 10. ”

Liao Yanmei looked at her admission ticket and said.

"What a coincidence, I'm also in the No. 10 exam room, you can just follow me. ”

After Qin Fei finished speaking, he looked at the map and walked straight forward.

"Really?"

Liao Yanmei was overjoyed, showed a sad face, and trotted behind Qin Fei with a small schoolbag on her back.

She looked up at Qin Fei's back from time to time.

Suddenly I felt very secure.

This experimental middle school is a newly built school.

The address is located on the outskirts of Longhuai City.

So the land here is probably not very valuable.

The campus is ridiculously large.

It is estimated to be three times more than that of Long Huaiyi.

I don't understand that the school buildings are far apart.

The two walked briskly for about seven or eight minutes.

Went up to the seventh floor of a building.

The bell is ringing for the exam.

Qin Fei stopped and pointed to an exam.

"It's here, it's the 10th exam room, you can go in quickly. ”

Liao Yanmei was relieved, very happy and was about to go inside.

only to find that Qin Fei not only did not come in.

Instead, he stepped back.

Rushed downstairs.

Liao Yanmei realized it later.

This Qin Fei's root is not this examination room.

He's just here to bring himself over.

Liao Yanmei was not anxious to enter her examination room.

Stop on the balcony in the hallway.

Look downstairs.

Soon saw Qin Fei's figure.

Galloping out like a horse.

Let's run after that.

His examination room was clearly long gone.

Liao Yanmei couldn't see Qin Fei's handsome figure until she couldn't see it.

I slowly walked into my own examination room.

I don't know why.

Filled with heavy emotion.

....

Of course, Qin Fei is not the No. 10 examination room.

And the No. 1 exam room

It's just that Liao Yanmei is a road idiot.

Just help her.

Anyway, others helped themselves in the car.

The grace of dripping water springs in return.

But when Qin Fei took this Liao Yanmei to look for a classroom.

I also paid attention to the location of my examination room.

So soon Qin Fei came to the door of the examination room.

Five minutes have passed since the official exam.

The examiner looked at Qin Fei sweating profusely.

It's not hard to do much.

After a brief check of the admission ticket, it was released.

Qin Fei sitting in his seat.

Don't be anxious to read the volume.

Calm yourself down first.

There is also the need to let the sweat evaporate first.

lest you stain your rolls.

The exam is held from 9 a.m. to 11 a.m.

A full two or two hours.

Actually, this is for most people.

are not enough.

But for the current Qin Fei.

That's more than enough.

This is the confidence that strength brings.

Finally.

Wait for your body to cool down.

Qin Fei began to gently scan the scroll.

The test paper consists of 10 fill-in-the-blank questions and 5 answer questions, each fill-in-the-blank question is worth 5 points, and the answer questions are 10 points each, and the full score of the whole paper is 100 points.

Qin Fei who finished reading the volume.

His brow furrowed.

Something seems wrong.

These topics....

It's not that Qin Fei is pretending.

It's really surprisingly simple.

It's a little simpler than the one I wrote for Chen Xinru last time.

It was far lower than Qin Fei's expectations.

Moreover, there seems to be a question in it, which is the original question written on the volume for Chen Xinru.

.....

Qin Fei's eyes narrowed, and he suddenly thought of something.

Could it be that someone really stole the question?

Or did this teacher happen to hit it?

Anyway.

Long Huai was over as soon as he hit the.

Qin Fei pursed his lips, didn't think about it anymore, and immediately started to write.

That's it.

The first question, which seems cumbersome, is actually very simple, which is a square difference formula and the conversion of stacked fractions, which can be written in thirty seconds.

The second question is to investigate the transformation of trigonometric functions, sinx+cosx=two, the root number of two, and the result of sin^4x+cos^4 is actually a squared problem, which can be written in one minute.

In the third question, let ^n=a0+a1x+a2x^2+...+aX^2n, then a1+a3+a5+...+a is equal to.

This question was a little more troublesome, Qin Fei turned his nose and assigned the formula.

^n=a0+a1x+a2x^2+...+aX^2n

Let x=1,3^n=a0+a1+a2+a3+.......+a+a

Let x=-11^n=a0-a1+a2-a3+........-a+a

3^n-1=2

a1+a3+a5+...+a=/2

The answer came in about two minutes.

Question 4, well, something, it's a geometric object... But it's also spicy chicken.

The fifth question is the application of Cartesian's rule of plus and minus. I remember that I swiped it in the system task.

Question 6... Needless to say, it's too simple.

It took about half an hour.

Qin Fei completed all the multiple-choice questions and didn't feel any special obstacles.

Next.

It's the answer to the question.

The problem is slightly more difficult.

One is the number series examined, the other is the proof of geometry, and the other is the mapping and set examined..... There is another one that has done the original question, and Qin Fei doesn't even want to take a second look.

The number series is still the same old thing, finding the maximum and minimum values.

Qin Fei directly used the Barochevsky drawing method to calculate the degree and extend the proof of congruence after calculating the degree, which is not much of a problem.

Only the mapping and collection of the last question is slightly new.

Let S be a 35-element set, and F is a set composed of some S-to-S mappings, and the set F satisfies the property P, and if any x,y belongs to S, there are f1,f2,,,fk belong to F so that:

fk)))=fk)))

Try to find the smallest positive integer m, satisfying: if F satisfies the property P, then it also satisfies the property P.

Considering X=, defining f)=,f, it can be seen from the meaning of the title that existence belongs to X, so that for arbitrary, can go through several mappings....

....

There are almost 40 minutes left.

Qin Fei finished all the test questions.

It is impossible to check.

It's impossible in this life.

Qin Fei didn't have this habit either.

....

So Qin Fei began to observe the people around him when he had nothing to do.

In the exam room.

All living beings are in different forms.

Some bite the tip of the pen.

Some gnaw their fingers.

Some scratch their scalps.

Some shake their thighs.

Some pinched people.

There are.

"Don't look around!"

The invigilator came to Qin Fei and reminded him in a low voice.

Qin Fei nodded obediently, and then asked.

"Can I submit the paper in advance?"

The teacher was stupid.

He has been engaged in Olympiad mathematics and other exams for more than 30 years.

This is the first time I have encountered such a request.

And look at his exam papers.

It's really finished.
