Being kissed by the school flower, I can't hide my status as a scholar

Chapter 2 He Can Solve It

"it is good!"

Su Jun put the mobile phone in her pocket casually, and walked towards the blackboard gracefully.

"Damn, is Su Jun so rigid?"

"Now let's brag a lot! This is a Mathematical Olympiad question."

"Xu Bowen, have you made it yet?"

A woman sitting in the front row touched the male classmate at the same table and asked.

Xu Bowen, the representative of the mathematics class, basically scores above 130 in every exam, very awesome.

Xu Bowen frowned and said, "Soon...soon."

"You are so powerful. I have a big head and I can't do anything. You will teach me later."

"it is good!"

"Then do you think Su Jun can solve it?"

"Just him?"

"Scumbag, if he can solve it, I will eat shit!"

Xu Bowen has already calculated most of the paper by experience. Although there is no result, he is not discouraged. After all, it is an Olympiad problem.

How can it be easily solved.

Therefore, he is not optimistic about Su Jun, and even thinks that he is just trying to please others.

Su Jun came to the stage and looked at this trigonometric function problem. Although he didn't listen to the lecture, in his mind, there were already several solutions to this problem.

sinα=2tan(α/2)/[1+tan^2(α/2)]
cosα=[1-tan^2(α/2)]/[1+tan^2(α/2)]
tanα=2tan(α/2)/[1-tan^2(α/2)]
……

Following Su Jun's step-by-step analysis, Xiao Ying's face slowly revealed an incredulous gaze.

Lin Yiling, who was at the same table, looked at Su Jun writing formulas on the blackboard quickly, without any appearance of a scumbag at all.

Can't help but mutter: "What did you write?"

"Hey, this formula can be used like this, why didn't I think of it!"

"Damn, this is too difficult! It's all trigonometric formulas, and it makes my head dizzy!"

"These formulas are too complicated. It seems that Su Jun is about to solve it, so I don't know if it's right!"

Following Su Jun's step-by-step analysis, everyone who was thinking of watching a joke began to frown and discuss.

Even Xu Bowen, the mathematics committee member, stared wide-eyed now, glanced at the blackboard in disbelief, and then looked at his own checking calculation.

As if he understood something, he checked again.

Zhang Xia, Xu Bowen's deskmate, frowned and stared at the blackboard: "Xu Bowen, do you think Su Jun is doing the right thing? Why does it feel so difficult?"

puff~
Su Jun finished writing the answer, blew on the chalk dust on her hand, and nodded very satisfied.

Then, amid everyone's doubts, he turned around and said, "Okay, this is just one of the solutions to this problem."

"Xu Bowen Xu Bowen, Su Jun has solved it, do you see it right?"

Only then did Zhang Xia notice that Xu Bowen next to him was frantically checking the calculations on the paper, but the answer hadn't come out yet, and compared to Su Jun's solution, it was even more incomprehensible to him!
When Xu Bowen heard this, he raised his head with an ugly expression.

He looked at it carefully, and the pen in his hand became tighter and tighter, and even a hole was poked in the proof paper by him.

"correct!"

"It turned out to be right!"

"Fuck, aren't you going to eat shit?"

Hearing this, Xu Bowen's face changed, and then he tore off his own proof paper, and held it tightly in his hand without saying a word.

Seeing that Xu Bowen, whom Zhang Xia admired the most, was a little angry, she didn't say much, but looked at Su Jun in surprise.

A boy sitting behind Xu Bowen said in disbelief, "Su Jun, I can't even understand what you wrote. You can explain it when you explain it?"

And Xiao Ying, the mathematics teacher behind, saw that Su Jun had solved it accurately, and she still couldn't believe it in her eyes.

"Well, this question is really difficult for you. This is just one of the solutions. Using our high school knowledge to answer it, the steps are less and the solution is faster!"

"Since you can't understand it, I'll use my junior high school knowledge to explain it to you again. It's just that this solution is more cumbersome to write!"

Seeing everyone looking at me blankly, the knowledge used in this question, except for some students who are relatively outstanding in mathematics, is basically incomprehensible to ordinary people.

"Hahaha..., then quickly solve it, we all want to see it!"

Hearing Su Jun's arrogant words, everyone laughed in unison.

A scumbag in mathematics, he even told them about junior high school and high school knowledge.

Su Jun ignored the ignorance of the students, and used the method of drawing auxiliary lines and corners to corners that she learned in junior high school to answer.

Almost half of the blackboard was filled with writing, and everyone's laughter gradually disappeared and became serious.

"Well, although it seems that there are more steps, this solution is easier to understand."

"However, we still need to pay attention to the trigonometric function values ​​of special angles, otherwise we will not get the answer in the end."

After Su Jun finished speaking, she threw away the chalk in her hand, and in the astonishment of everyone and the radiant eyes of the class teacher Xiao Ying, she turned and returned to her seat.
