Super Scholar: Start with a low regulatory score!

Chapter 367 Can't even do such a simple question, is it a fake Hua Qingsheng?
What?
Someone actually said that in such a similar scene, the good-looking girl who appears is almost the heroine?
Ah bah, how is it possible?

Jiang Nan has a sweetheart, right?
Talk nonsense.

but……

Some big guesses are good. This moment of pretentiousness has already appeared, how can they stand still?

Speaking of...

It's been a long time since Jiangnan put on a show.

The skills are rusty!

The name of being a God-forcer has gradually faded away.

[sp: The above is the self-conjecture of some readers, and it is by no means Jiangnan's inner activities ヾ(: 3ヾ). 】

Actually...

The moment I saw this girl.

Jiang Nan was surprised and almost jumped up.

of course.

It wasn't because he knew the other person, but it was purely an instinctive reaction, subconsciously thinking that he had been recognized.

"No, no, no!"

"I just came to Huaqing on the second day, and I was recognized by someone? Doesn't that mean I will have no peace in the future?"

"It's not like the scene in Jiangcheng will be repeated again! Wherever you go, you will be a fan of little brothers and sisters?"

"I don't want to be like this!"

"I really just want to make progress with peace of mind."

"Can you still let me study well?"

In an instant.

Millions of thoughts flashed through Jiang Nan's mind, and the thoughts flowed so fast that he didn't even realize it.

"Impossible, it should be impossible."

"It should be impossible for her to recognize me."

"After all, this is Yanjing, Huaqing University, not Jiangcheng, not No. [-] Middle School. How could she know me?"

"What's more, I went to Huaqing, but I greeted Tang Xiaohu and Yi Qiu, let them keep it secret for now."

"And I also wear a super peaked cap and a flat mirror. The combination of the two can barely reduce my appearance and temperament. If you are not very familiar with me, you should not recognize it."

"Well, she probably doesn't know me!"

next second.

Jiang Nan came to his senses and made a judgment in his heart. The other party didn't come to strike up a conversation because he knew him, maybe he really just wanted to ask a question.

after all……

This is the library of Huaqing University.

Those who can still study here during the summer vacation.

It is definitely the kind of super academic who loves learning very much. It is normal to ask if you don't understand.

Thinking of this, Jiangnan put the super plane mirror on the bridge of his nose, nodded slightly and said, "Yes, you can ask!"

Emphasize one sentence.

He didn't agree because the other party was good-looking, after all, he wasn't that kind of good-looking party (˙o˙).

The more beautiful my girlfriend is, the better.

Besides.

How does appearance matter to him?
And the reason why he agreed was purely because he wanted to test the results of his day's study through the other party's questions on the premise that the other party did not recognize him.

He has just arrived at university, but after reading a day of math books, he really has no idea what his specific math level is.

And the other party is a top student from Huaqing, so the question asked should be a bit difficult, right?
You can definitely check your own level.

"Thank you classmate!"

The little girl with ponytails smiled sweetly at Jiangnan, thanked him in a low voice, then handed the pen and paper to Jiangnan, pointed and said: "This, this, and this, just these three questions, I've been thinking about it for a long time and haven't figured it out!"

"Ok!"

Jiang Nan nodded and looked at the paper.

only see...

第一题：已知曲线C：x^2+2y^2-z=6，4x+2y+z=30，求C上的点到xoy坐标面距离的最大值。

Jiangnan: "(￣_,￣)???"

Glancing at the girl next to him, his face froze slightly.

It's not because he can't solve the problem.

Instead, he wondered if this girl was teasing him.

As a Huaqing student at Dongyun's top university, is the difficulty of the questions asked? ? ? ?
funny right? ?
Or was it because she was so handsome that this girl just found a reason to strike up a conversation? ?

Most likely the latter.

But Jiang Nan took a look.

Judging from his micro-expression analysis skills, it seems that this girl is not here to strike up a conversation.

and so……

"This question is very simple, it is a Lagrangian function problem, I just saw it in the book this morning."

Jiangnan took the pen and paper, began to write and explained: "Assume that the Lagrangian function L(x, y, z, γ, μ)=z^2+γ(x^2+2y^2-z -6)+μ(4x+2y+z-30).

L'x=2xγ+4u=0.

L'y=4yγ+2u=0.

L'z=2z－γ+u=0.

x^2+2y^2=6.

4x+2y+z=30.

Solve the stagnation points: (4, 1, 12), (-8, -2, 66).

The distance between the point (-8, -2, 66) on C and the xoy plane is at most 66. "

Less than half a minute.

Jiang Nan finished speaking and writing the topic, while Lin Qingya who was next to him just stared blankly.

"This……"

"This this……"

"Am I dazzled?"

"Is there something wrong with your ears?"

"I've been thinking about this question for a long time without a clue! But he didn't even think about it, so he just solved it?"

"Half a minute, only half a minute! Are all boys from the math department so fast?"

Lin Qingya stared blankly at the paper, then looked at Jiangnan in disbelief, extremely surprised.

but……

This is not the end.

But it was just the beginning of her surprise.

just because...

After Jiang Nan finished solving one problem, he started the second problem regardless of whether Lin Qingya understood or not.

“设有界区域D是x^2+y^2=1和直线y=x以及x轴在第一象限围ffDe^(x+y)^2(x^2-y^2)dxdy。”

This question...

It's slightly interesting.

But it's just kind of interesting.

Is it difficult?

There is no difficulty at all!

“解：省略52个步骤……最终答案为：1/8e^2-1/4e+1/8。”

Ah!
It took almost 1 minutes.

Then there is the third question.

"Assuming n is a positive integer, y=yn(x) is the differential equation xy'-(n+1)y=0 satisfying the condition y.

(1) Find yn(x).

(2) Find the convergence region and sum function of the series [1, +∞] yn(x). "

I can tell.

This girl is not deeply involved in functions.

otherwise.

Nor will three questions in a row be related to functions.

But in fact.

As long as you read all the books on functions like Jiangnan, it should not be too easy to do these questions.

“解：（1）yn（x）=1/n（n+1）*x^(x+1）；（2）收敛域为【－1，1】，级和函数S(x)=(1－x）ln(1－x)+x，x属于【－1，1），或者1，x=1。”

Ah!
Three questions.

Add up to no more than 3 minutes.

Jiang Nan finished everything, and then handed the pen and paper to Lin Qingya, "The answer is that, it's very simple, just read a few more books about functions."

"But you can't?"

"Could it be that you, like me, haven't entered university yet, but came to Huaqing Library for self-study in advance?"

Jiang Nan was very suspicious.

This sudden girl was not a student of Huaqing, otherwise her math level would not be so good.

I only read the book for a day and I can figure it out. If I am really a top student in Huaqing, I think I can solve it easily!

But Lin Qingya didn't know how to do it.

That excludes all the impossible, and the rest, no matter how impossible, is the truth.

That is……

Lin Qingya is a fake Hua Qingsheng.

however……

Hear what Jiangnan said.

Lin Qingya, who was still in shock, blushed instantly with that pretty face, and almost subconsciously retorted: "I... I'm different, I'm a postgraduate entrance examination student..."

The words stopped abruptly.

just because...

Lin Qingya suddenly realized a problem, what did Jiangnan say just now?Jiang Nan said that he has not yet entered the university, but he just came to the library to study in advance?
This……

How can this be?

Although I am not a mathematics major, and I have just finished my junior year and will soon enter my senior year, most of the advanced mathematics knowledge I have learned has been returned to the mathematics teacher.

But it doesn't mean she doesn't have a little eyesight!
She can be sure.

The three questions I asked myself were still very difficult.

After all, the paper she took was the real test for the postgraduate entrance examination a few years ago, and it was the final one.
