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.
Soon he encountered problems again.
"Ms. Qin..."
Seeing this geometric equation, Qin Luo smiled bitterly.
You may not be able to speak out. I think you need to start in elementary school...
...
When Qin Luo was solving the problem, in a corner not far from Qin Luo, several scorching eyes stared at Qin Luo, or Li Shaolin beside him.
At this moment, Qin Guoyang set off a terrible wave in his heart.
To be honest, when Chen Qiangsheng said that Li Shaolin's prodigal son was turning back, Qin Guoyang had a little doubt in his heart.
After all, a person who is used to playing can hardly be interested in learning.
But now, when he saw Li Shaolin holding textbooks 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 why.
Thinking of this, he beckoned to Qin Guotao.
"Guo Tao, come here." Qin Guoyang said.
"Dad?" After three steps and two steps, Qin Guotao came to his father.
"What the **** is going on?" Qin Guoyang asked.
what happened?
Hearing Qin Guoyang's words, Qin Guotao's mouth twitched.
He really couldn't tell what was going on.
Could it be that the spark of learning is coming?
Or does it mean that mathematics can exercise logical relationships and make people a martial artist?
No matter which one, it sounds like it's telling a book.
After hesitating for a while, Qin Guotao gritted his teeth and said, "Dad, I said Li Shaolin's brain is broken, don't you believe it?"
letter!
Trust a hammer!
Hearing his son's words, Qin Guo frowned and said sternly: ‘Talking! ’
"Uh, Qin Luo said that mathematics can train logical thinking and make people better, but Li Shaolin believed it..." Qin Guotao said.
