Chapter 5 Work hard, you can also become a scholar

The picture of imagining the soaring hegemony in middle school did not appear. Instead, Qin Luo's eyes were full of flowers, and several Chinese characters with Dou Da appeared in front of Qin Luo.

"The value of this book is too high, and the host is not qualified to read it at this moment."

"..." If possible, Qin Luo would like to find a crack in the ground to get in.

Helpless, Qin Luo had no choice but to give up solving the world's problems, and instead went to the book "Trigonometric Function Expansion and Analysis".

"This kid has really changed his mind?" Li Wei muttered to himself, watching Qin Luo put down "Goldbach Conjecture" and move on to the next "Trigonometry".

It's not that he hasn't seen the prodigal son turn around for more than 20 years, but this is the first time Li Wei has seen a prodigal son like Qin Luo who has no warning.

"I'd like to see how long you can pretend."

Li Wei didn't leave in a hurry, but just stood there and looked at Qin Luo.

Five minutes, ten minutes, half an hour...

Qin Luo still had no intention of putting down the book in his hand.

He seemed to be immersed in it.

Li Wei was dumbfounded.

"Scholarship value +1"

"Scholarship value +1"

Qin Luo didn't know about Li Wei's arrival at all. He was looking at his increasing academic hegemony value with delight.

At this moment, Qin Luo felt that his thin body was getting stronger, and his empty spirit was being replenished. A better tomorrow is beckoning to you.

"Cough, classmate, how do I do this question?" Just when Qin Luo was immersed in the ocean of learning, a nice girl pulled him back to reality.

Looking back, I saw a pretty girl walking over with a scratch paper.

"That question, let's hear it." Qin Luo responded generously.

As an upright scholar, Qin Luo felt that he had to help the scumbag.

"Thank you." The cute girl whispered thank you, and she handed the textbook in front of Qin Luo to Qin Luo.

Trigonometry?

The curve Ycosx+2y-1=0, first translate 2/π units to the right along the X axis, and translate 1 unit downward along the Y axis, and the curve equation is obtained:

I just saw trigonometric functions just now, so let's try it out.

Taking over the pen and paper in the hands of the cute girl, Qin Luo began to calculate quickly.

Arrange the formula: Y=1/2+cos(x-π/2)-1, because the original curve is to be turned to the right and down to a building of 2/π and 1 unit respectively, so the formula can be directly transformed into : (y+1)cos(x-π/2)+(y+1)-1=0.

In just two minutes, Qin Luo wrote the answer: "It's solved."

"What? Solved it? So fast?" Lin Shanshan looked at Qin Luo in disbelief. He thought about this question for a long time and couldn't solve it, but in Qin Luo's hands, he solved it in just two or three minutes?

"See for yourself."

Lin Shanshan was skeptical, and he carefully recalculated the questions according to Qin Luo's steps.

"...that's really the answer!"

Lin Shanshan was stunned for a while.

"The host's massive amount of knowledge has successfully aroused the shock of others, and obtained 10 points of academic masters." The system's prompt sounded at the right time.

Qin Luo's Xueba value increased by another 10 points.

So beautiful~

"By the way, classmate, you just entered high school, what class are you in?" Qin Luo asked curiously.

Lin Shanshan blushed all of a sudden, and said with a blushing face, "I'm in the third year of high school..."

"Work hard, you will become a scholar like me in the future." Qin Luo looked at her seriously and said encouragingly.
