v10 Chapter 1317： Give you a math book (1/2)

This is a calculus in advanced mathematics.

The question is: X²-2xy+y³=6 determine y is a function of x, find Y”.

Emmmm, you may not believe it. Based on your level, it is better to learn from outstanding mathematics.

But whenever he said these words, Qin Luosheng swallowed it back.

Just give him a chance.

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

As a world-renowned academic tyrant, he brings paper and pen not only for signing, but also for solving problems anytime and anywhere.

2x-2y-2xy’+3y²y’=0

Y’=2x-3y/2x-3y²

y”=(2-3y’)(2x-3y²)-(2x-2y)(2-6yy’)/(2x-3y²)²

...

In less than a minute, Qin Luo had already completed the problem.

”Understand?” Qin Luo turned to look at Li Shaolin.

”Ahem, understand!” Li Shaolin nodded seriously.

Qin Luo smiled and said: ”Then tell me, who am I writing about?”

What is written?

The corners of Li Shaolin's mouth twitched wildly.

After a long silence, Li Shaolin said seriously: ”Numbers!”

God's special number!

No, I also know it is a number!

No, I am not talking about this!

”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 was not that Qin Luo looked down on Li Shaolin, but Li Shaolin's strength was there, and Qin Luo decided to teach in accordance with his aptitude.

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

”Thank you Teacher Qin!”

Holding the mobile phone, Li Shaolin was happy.
