Become Top Student In A Second

As soon as Qin Luo's voice fell, Lin Shanshan's face became more red.

Not because of shyness, but because of anger.

Did you solve a math problem? What the hell! You deserve to be in the library alone.

"Hum." With a cold hum, Lin Shanshan turned her head and left.

Let's go. Anyway, Qin Luo doesn't care. Lin Shanshan is just an experienced baby for him.

Money is precious, sister's price is higher, if it is knowledge, both can be thrown away.

Xueba doesn't need that stuff.

Soon, Qin Luo returned to the state.

"Xueba value + 1"

"Xueba value + 1"

"..." If you ask Qin Luo what is the most beautiful sound in the world, Qin Luo answers: the prompt sound of the system.

Where Qin Luo could not see, Li Wei's eyes were fixed on it.

He's going crazy!

He thought that Qin Luo would take the opportunity of reading in the library, but now Qin Luo is really studying in front of him, and he is very serious. He even helps Lin Shanshan to answer questions.

That's Lin Shanshan. She's one of the top ten students in the grade.

No, I have to go and see what kind of medicine Qin Luo took! Li Wei's heart was surging, and he immediately walked from where Qin Luo was.

"Cough!" Li Wei stood not far from qinluo and coughed gently.

However, Qin Luo, who had been immersed in the ocean of knowledge, did not look up at all when he heard Li Wei's signal.

"Cough, cough, cough!" Li Wei's face turned black and his voice increased a little.

"Who ah, if you cough, go to the infirmary, don't affect my reading. Eh, Miss Li, how did you come?" Qin Luo raised his head and looked at him standing on the side. His face was red. Li Wei was puzzled.

All of a sudden, Qin Luo frowned and said, "Teacher Li, if you cough, you can go to the infirmary for early treatment and early recovery."

Early treatment, early recovery? Although this sounds reasonable, but from Qin Luo's mouth, why is it so awkward?

It's like having a terminal illness.

Pooh, Pooh, Pooh! I'm in good health. I don't even have a cough.

"Qin Luo, reading is very serious." Li Wei swept the book, a smile: "trigonometric function expansion and analysis is good, what do not understand the place is not, do not understand the words can ask the teacher."

"No, Mr. Li. I have basically understood it." Qin Luo didn't raise his head.

A Book of trigonometric functions is worth 10 points. Now Qin Luo has got eight of them.

It can be said that he has understood 80% of the content, and the remaining 20% will be understood if he looks at it again.

"Oh?" Li Wei frowned and continued to ask, "are you sure you understand?"

"Xueba value + 1"

"nine points!"

Qin Luo's smile, more and more Sheng: "sure."

"Good! Then I'll test you. "

With these words, Li Weishun picked up the remaining draft paper on the table and began to write.

"What is the range of X that makes SiNx > cosx hold in 0,2 π?"

The trunk is very short, but the difficulty is not low at all.

He has almost all the knowledge of trigonometric functions, such as intersection, tangency, inclusion, and even drawing

"Mr. Li, are you sure you want me to do this problem?" Looking at such a "straightforward" topic, Qin Luo widened his eyes.

After getting the nine point Xueba integral, the original trigonometric function is so simple.
