Chapter 1317 Give You a Math Book

This is a calculus in advanced mathematics.

The title is: X-2xy+y=6 to determine that y is a function of x, find Y".

Emmmm, you may not believe it when you say it, but at your level, it is better to start with outstanding mathematics.

But every time these words came out of his mouth, Qin Luo swallowed them back.

Just give him a chance.

After thinking about it, Qin Luo asked for a pen and paper from his pocket.

As a world-famous scholar, bringing a pen and paper is not only for signing, but also for solving problems anytime, anywhere.

2x-2y-2xy'+3yy'=0

Y'=2x-3y/2x-3y

y"=(2-3y')(2x-3y)-(2x-2y)(2-6yy')/(2x-3y)

...

In less than a minute, Qin Luo has completed the problem solving.

"Do you understand?" Qin Luo turned to look at Li Shaolin.

"Cough, I understand!" Li Shaolin nodded seriously.

Qin Luo smiled and said, "Then tell me, who and what did I write?"

What is written?

Li Shaolin's mouth twitched wildly.

After a long silence, Li Shaolin said seriously, "Numbers!"

God's numbers!

No, I know it's numbers too!

No, that's not what I'm talking about!

"Forget it, I don't think advanced mathematics is suitable for you. You should start with the content of junior high school."

While talking, Qin Luo clicked on Baidu and searched for a "seventh grade" math textbook.

It's not that Qin Luo looked down on Li Shaolin, but that Li Shaolin's strength was there, and Qin Luo decided to teach students according to their aptitude.

Alas, there are not many teachers as good as me...

"Thank you, Teacher Qin!"

Holding the mobile phone, Li Shaolin was overjoyed.

Soon he ran into problems again.

"Mr. Qin..."

Looking at this geometric equation, Qin Luo smiled wryly.

Say it you may not. I think you need to start in elementary school...

...

Just as Qin Luo was solving the problem, in a corner not far from Qin Luo, a few scorching eyes stared at Qin Luo, or Li Shaolin beside him.

At this moment, Qin Guoyang set off a storm in his heart.

To be honest, when Chen Qiangsheng said that Li Shaolin's prodigal son was back, Qin Guoyang had some doubts in his heart.

After all, it is difficult for a person who is used to play to be interested in learning.

But now, when he saw Li Shaolin holding a textbook and studying mathematics with his own eyes, Qin Guoyang was shocked on the spot.

It turns out that the sun can really come out from the west!

At this moment, he wanted to know the reason.

Thinking of this, he waved to Qin Guotao.

"Guo Tao, come here." Qin Guoyang said.

"Dad?" Qin Guotao came to his father in three steps and two steps.

"What the hell is going on?" Qin Guoyang asked.

what happened?

Hearing Qin Guoyang's words, Qin Guotao's mouth twitched.

What was going on, he really couldn't say.

Could it be that there is a spark of learning coming?

Or that mathematics can exercise logical relationships and turn people into martial arts masters?

Either way, it sounds like they're talking about a book.

After hesitating for a while, Qin Guotao gritted his teeth and said, "Dad, do you believe me when I say Li Shaolin's brain is broken?"

letter!

Trust a hammer!

Hearing his son's words, Qin Guoyang frowned and said sternly: 'Speak human words! ’

"Uh, Qin Luo said that mathematics can exercise logical thinking and can make people better, but Li Shaolin believed it..." Qin Guotao said.
