Super Xueba: Start With A Low Control Score!

Chapter 341 The second math is still easy to do!

Southern God!

A legendary name.

So big Dongyun, as long as they are concerned about the four international competitions, schools, and exams, few people don’t know it.

certainly!

There are no children in the family who are in high school, nor are they studying, except for those who never pay attention to exams.

But even so.

Nanshen has a lot of fans.

It can be said like this.

If Jiang Nan enters the network.

As soon as he opens the bib, or registers the fighting number.

It’s not always necessary to get a million fans a day, but it’s easy to get a million fans, and it’s so simple.

As the so-called love is deep and responsible.

The people who criticized Jiangcheng Daily for being more vicious are actually people who are extremely concerned about the college entrance examination.

The reason is that the population in the Jiangcheng Daily interview was too arrogant, thinking that it was a kind of blasphemy on the college entrance examination.

That’s why they are filled with righteous indignation.

And now…

When it was discovered that the person was actually Jiang Nan.

This attitude immediately changed a hundred and eighty degrees.

“Ciao!”

“I actually attacked the Southern God. This is like a flood of water rushing into the Dragon King Temple. I don’t know Jingshan jade!”

“Southern God, that is Eternal God!”

“Everyone got the first place in the four international competitions, breaking the record in the history of the four competitions. With his strength, isn’t this so-called college entrance examination handy?”

“Although no one has scored full marks in Chinese for more than 20 years, who is Nanshen? Nanshen is a person who specializes in breaking the limit and creating miracles!”

“Since he said that the Chinese test is simple, the composition is simple, and he can get full marks, he will get full marks out of ten.”

“This person can’t spray!”

“I’ve been bragging all my life and I’ve never served anyone, but for Nanshen, that’s absolutely convincing.”

“…”

What is double standard?

This is called double standard.

How harsh the criticism just now, how high they are now, and they are just ordinary fans of Jiang Nan.

When Jiang Nan’s hardcore fan saw Jiang Nan’s handsome face that made people feverish and crazy inside.

Suddenly.

Both the huge bib and the sound of the fight quake.

“Ahhhhhhh!”

“Southern God, that’s the Southern God!”

“Idol, that’s my only idol!”

“Husband, that’s my husband alone!”

“Quickly, the people above quickly get out of the way, only I can watch this video!”

“Finally, I finally saw my husband up close again, he is still so handsome and handsome.”

“Idols are idols, their words and deeds are so simple and unpretentious, but they are deeply moving!”

“Especially the last paragraph [The universe is undecided, you and I are both dark horses, fighting back and forth, success or failure depends on the present, see you at the top of the mountain], it is really exciting to hear!”

“It is estimated that only Southern God in this world is qualified to say such a wise saying!”

“For Nanshen, the college entrance examination is just fun, he actually stood on the top of the mountain long ago!”

“And we…”

“It’s time to follow in his footsteps!”

“Nan Shen, see you on the top of the mountain!”

“…”

Originally, there were not many fans of the bib and Douyin accounts of Jiangcheng Daily, but at the moment they are on the rise.

Fifty thousand, one hundred thousand, three hundred thousand, five hundred thousand…

The reason for this is simply that the video interviewing Jiang Nan was posted without mosaics.

Almost all fans of Jiang Nan, as soon as they saw it, they left a message under the video.

As for those who originally attacked Mosaic, they also withdrew their comments and praised Jiangcheng Daily.

So that…

Jiangcheng Daily went viral in an instant.

Regarding Jiang Nan’s first step out of the examination room, he said that the paper is simple, the composition is simple, and the topic can get full marks.

It also quickly soared to the top three on the bib and Douyin hot list, and even hit the first place.

This first, but the real first, and not the one with the slightest moisture.

certainly!

This is a small episode, not worth mentioning.

…

the other side.

Jiang Nan didn’t know anything about the Internet. After all, he never played with snoods, and he didn’t know much about fighting sounds.

certainly.

Even if I knew it, I wouldn’t care.

The only thing he cares about now is the college entrance examination.

Although he handed in the papers in advance, he did not immediately return to the third middle school. Instead, he waited until both Bai Yingying and Fatty Wang had handed in the papers before going with him, returning to the third middle school for lunch and rest.

Until half past two in the afternoon.

Only then came back to No. 1 Middle School and walked into the examination room.

“Jingle Bell!”

At three o’clock in the afternoon, as the bell rang, the second mathematics of the college entrance examination officially began.

Once the paper is in hand.

Jiang Nan didn’t think much, so he wrote the answer directly.

1. Let the set A={x|-2A, {2}. B, {2, 3}.

C, {3, 4,}. D, {2, 3, 4}.

…

3. Given the radius of the bottom surface of the cone √2, and the expanded side view is a semicircle, the generatrix length of the cone is B.

A, 2. B, 2√2.

C, 4. D, 4√2.

…

These questions couldn’t be easier!

There is no need to explain at all.

Jiang Nan finished the nine multiple-choice questions and three multiple-choice questions in one go, which are BCBBACBDBD…

Then there are four fill-in-the-blank questions and six answer questions.

Nine in front.

He also breathed one another at a time, and it took him a few more minutes until the final finale.

Not because the question is difficult.

But it was Jiang Nan’s serious attitude.

Actually.

This question is really just so-so.

Suspension is also the difficulty of the Olympiad finals, even the ultimate test can not be compared, let alone international competitions.

The original title is as follows…

“22, (12 points).

Known function f(x)=x(1-lnx).

(1) Discuss the monotonicity of f(x).

(2) Let a, b be two unequal positive numbers, and blna-alnb=a-b, prove: 2<1/a+1/b<e. "

No one can do this question, right?

If there is.

That's not working hard enough in normal times!

Jiang Nan quickly wrote the answer.

"Solution: (1) Find the derivative to obtain F'(x)=-ln(x). According to the sign of f(x), we know that f(x) increases monotonically on (0, 1), at (1, ∞) The ups are monotonously decreasing."

That's right.

The first question is that simple.

Get it done in one sentence, it's no different from sending points.

If you can’t get this point, either you’ve been fishing too much on weekdays, or the exam is too stressful and you don’t know how to plan the time for the questions properly, so you give it up.

In comparison.

The second question is a little more complicated.

Of course, it's just a little more complicated.

As long as the foundation is solid and the logic of thinking is strong enough, it is not a problem to get it done easily.

The answer is as follows…

"Solution: (2) Prove: Let u=1/a, v=1/b, and simplify to get u(1-ln(u))=v(1-ln(v)), that is, f(u)= f(v).

At this point we only need to prove that 2 is known by the Law of Robida…

…

According to the first question, the monotonicity f(x) of the function is greater than 0, which is always true for any x ∈ (0, e).

Let g(x)=f(x)-f(2-x), where x∈(0,1), then g'(x)=-ln(1-x)-ln(x),g”( x)=2(x-1)/x(2-x)<0, so g(x) decreases monotonically in the interval (0, 1).

…

And h(1)=f(1)-f(e-1) is greater than 0, so h(x) is greater than 0. For x∈(0,1), it is always true. If x=u is taken, f(u) is greater than f (e一u), so…

f(v)=f(u) is greater than f(e-u).

Then from f(x) monotonically decreasing in the interval (1, e), v…

The focus of this question lies in the Law of Robida and the derivation, and this derivation is divided into the first derivation and the second derivation.

There is a slight trouble.

But it took Jiang Nan a few minutes to get it done easily, and then… again, he fell asleep at the table.

Invigilator: (｡･᷄ཀ･᷅)? ?

Surrounding students: (｡･᷄ཀ･᷅)? ?

sp: After the college entrance examination is completed today, it must be changed tomorrow, 200 gifts plus one change, if the upper limit is not capped, Ollie will give it.
