Chapter 5 Work hard, you too can become a top student
The picture of the soaring hegemony in the middle school did not appear, but Qin Luo's eyes flashed, and several large Chinese characters appeared in front of Qin Luo.
"The value of the book is too high, and the host is not qualified to read it at this moment."
"..." If possible, Qin Luo really wanted 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 went to the next book "Expansion and Analysis of Trigonometric Functions".
"This kid has really changed his sex?" Seeing Qin Luo put down "Goldbach's Conjecture" and go to the next "Trigonometric Functions", Li Wei muttered to himself.
It's not that he hasn't seen a prodigal son turn his head back in the industry for more than 20 years, but this is the first time Li Wei has seen a prodigal son like Qin Luo turn back without warning.
"I want to see how long you can pretend."
Li Wei didn't leave in a hurry, but stood tightly on the spot, looking at Qin Luo.
5 minute, 10 minutes, half an hour...
Qin Luo still didn't intend to put down the book in his hand.
He seemed to be immersed in it.
Li Wei was dumbfounded.
"Student master value +1"
"Student master value +1"
Qin Luo didn't know about Li Wei's arrival at all, he was looking at his ever-increasing academic master value with glee, it was like chewing on Xuanmai and couldn't stop.
At this moment, Qin Luo felt that his thin body was gradually getting stronger, and his empty spirit was being replenished.A better tomorrow is waving to myself.
"Ahem, classmate, may I ask how to do this question?" Just as Qin Luo was immersed in the ocean of study, a pleasant female voice brought him back to reality.
Looking back, I saw a handsome girl walking over with a draft paper.
"Which question, let's talk about it." Qin Luo responded generously.
As an upright academic bully, Qin Luo felt that he had to help the poor academics.
"Thank you." The cute girl whispered thank you, and then handed the textbook in front of Qin Luo.
Trigonometry?
For the curve Ycosx+2y-1=0, first translate 2/π units to the right along the X axis, and then translate 1 unit down along the Y axis, and the equation of the curve is:
I happened to read trigonometric functions just now, so let's try my skills.
Taking the pen and paper from the cute girl's hand, Qin Luo began to calculate quickly.
整理式子：Y=1/2+cos(x-π/2)-1，因为要将原曲线向右，向下分别一栋2/π和1个单位，所以可以直接将式子化为：（y+1）cos(x-π/2)+（y+1）-1=0。
In just 2 minutes, Qin Luo wrote the answer: "It's solved."
"What? Solved it? So fast?" Lin Shanshan looked at Qin Luo in disbelief. She had been thinking about this problem for a long time, but she couldn't solve it, but in Qin Luo's hands, she solved it in just two or three minutes. ?
"See for yourself."
Lin Shanshan was skeptical, and he carefully recalculated the question according to Qin Luo's steps.
"...That's really the answer!"
Lin Shanshan was stunned for a moment.
"The host's vast amount of knowledge has successfully shocked others, and he has obtained 10 points of mastery." The system's prompt sounded at the right time.
Qin Luo's student master value increased by another 10 points.
Beautiful~
"By the way, classmate, you just entered high school, which class are you in?" Qin Luo asked curiously.
Lin Shanshan blushed all of a sudden, and said with a pretty face, "I'm in the third year of high school..."
"Work hard, you will become a top student like me in the future." Qin Luo looked at her seriously and said encouragingly.
