Kuaishou's heartthrob host, he just wants to make a career

"Can you tell me about your problem-solving process?" Zhou Mian asked while suppressing the shock in his heart.

"This question is a very normal definite integral question. As long as there is a geometric meaning of the definite integral, you can know that the area enclosed by the upper half circle and the X axis..."

Lin Yan's thinking in solving the problem was very clear, and even Zhou Mian couldn't make a mistake. He thought that the shock this young man gave him was over, but he didn't expect to hear him say it again.

"In fact, there is another solution to this question, which is to use the substitution method to solve it, let x-1=sint (negative half of π≤1≤...), and finally get the area integral of half of π."

Zhou Mian followed his idea of ​​solving the problem with relish, and said happily, "You know how to change Yuan?"

The surprise this boy brought him was not just a shock.

Genius, absolutely genius!

When the passenger next to him heard the conversation between these two, he instantly felt that his IQ had been hit. Good guy, he is indeed a student of Jiahe. He stuffs it back.

Lin Yan stretched out his hand, "I won..."

Although Zhou Mian was reluctant to part with this pen, he hoped to concede the bet.

Lin Yan accepted the pen, "If I remember correctly, you should have come up with a similar question based on the question on the page I just read, right?"

"That's right, you actually figured it out. Which first grade class are you in? What's your name? Are you in Liu Qin's class?"

Liu Qin's homeroom teacher and math teacher in the first-grade rocket class is also his old classmate, and they are all members of the Mathematical Research Center of Qingda University.

This little genius, how did you hear Liu Qin mention it before?

When it was almost time to stop, Lin Yan took off his glasses and put them back in the box, "No. It's class F, Su Yanxi."

Class F?

Zhou Mian was stunned for a moment, such a powerful boy is only in class F?

The bus had already stopped at a platform, Lin Yan: "I've arrived."

Zhou Mian thought so fast, he just started talking.

"Little classmate, my name is Zhou Mian."

Lin Yan nodded: "Okay, I remember you."

After getting off the car, Lin Yan looked at the pen in his hand and called out 2333.

[2333, do you know who Zhou Mian is? 】

2333: "The name Zhou Mian didn't appear in the main mission, and I couldn't find his information."

Lin Yan frowned, "Change someone else and search for Liu Qin's personal information?"

2333: "Liu Qin, Jiahe School, head teacher of the first-year rocket class, member of Qingda Mathematics Research Institute."

Hearing the words Qingda Institute of Mathematics, Lin Yan immediately understood that this bus circled more than half of the city, and the end of the bus was not far from Qingda. Zhou Mian should be Qingda's teacher.

interesting!

-

While Lin Yan was guessing Zhou Mian's identity here, Zhou Mian also excitedly called Liu Qin and asked him if he knew Su Yanxi, a math genius in his class F?

Liu Qin: "Also a math genius? I have led so many students, this year is the worst."

Zhou Mian: "..."

"Okay, I say this sentence every year. Seriously, do you know me?"

"Su Yanxi, what can you do with him?"

Zhou Mian hastily told the story from the beginning to the end of the encounter with Lin Yan on the bus just now.

Liu Qin asked in disbelief, "Is he really that good?"

Zhou Mian: "Why am I lying to you? This little classmate even won me a pen, which was a reward from the Academy of Sciences some time ago."

"Tsk, if this kid is really that good. I happen to be in the office, so I'll check it out for you." They are all math teachers. If there is such a good seed in the school, of course they will not let it go.

"Quick check. I'll wait for you..."

Liu Qin asked for the information of Class F from Li Yu, and when he saw Su Yanxi's information, his brows almost frowned, "Are you sure the person you're talking about is Su Yanxi, not Jiang Hang?"
