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

Lin Yan swiped his card in the car and sat in the back seat. While talking to 2333, he took out a book on advanced mathematics and calculus. There were many questions on it. It was worth reading. By the way, he could review what he had learned before.

As soon as he sat down, a middle-aged man with a bald head sat next to him. Lin Yan turned to the side and continued to immerse himself in the question.

When Lin Yan buried his head in reading the question, he didn't know that the middle-aged man beside him had been watching him. After the bus passed two stops, he finally couldn't help but speak.

"Student, are you a student of Jiahe?"

Lin Yan found that as long as the mysteries in mathematics are found, he will find it very interesting, so he fell in love with it. He really enjoyed the pleasure of solving a problem and finding the correct answer.

So he was fascinated by it, and when he raised his head to answer, he looked at the person next to him and was still confused.

The middle-aged man resentfully said, "Did I disturb your study?"

Lin Yan said bluntly, "A little bit..."

It is inconvenient to hold a pen and paper on the bus. He will solve the problem in his head. Although the bus is noisy, if he does not disturb him, he will not be affected.

But this person obviously bothered him.

Middle-aged man: "..."

He was just a little more polite, the little classmate really didn't save any face.He pointed to the book in Lin Yan's hand, "Are you a sophomore or a graduate?"

The third-year graduates need to study by themselves in the evening, and he prefers that Lin Yan is a second-year student.

Lin Yan adjusted his glasses, feeling puzzled by this strange man's conversation, but he still said, "First grade..."

"First grade?" The man became more interested in him after listening to it, "Then can you understand the book in your hand?"

Lin Yan said in a low-key manner: "It's okay..."

The middle-aged man said enthusiastically: "Then I will give you a debut question, do you dare to do it?"

If the first grade can understand the questions in this calculus book, isn't it a genius?

The main reason was that he was still wearing Jiahe's school uniform, which made Zhou Mian more convinced of his guess.

Especially for the first graders this year, there is a student named Jiang Hang, whose family is from a family of mathematics. In junior high school, he participated in the National Mathematical Olympiad Junior High School No.1.

He made a question?

Lin Yan also became interested, and agreed, "Okay..."

Zhou Mian likes this kind of straightforward students, he glanced at the page he happened to read, "Then I'll just post it casually, listen carefully, ∫ (upper limit 1 down line 0) root sign down 2x-x2dx= How many?"

After finishing speaking, he reminded: "Do you need a pen and draft paper? There is no time limit. As long as you solve it before you arrive at the station, you will win."

Lin Yan raised his eyebrows, "Then if I win, what good will it do?"

Zhou Mian came out in a hurry today, without bringing anything. He touched the pen on his chest. Although it hurt, he took it out as a bet, "If you win, this pen will be given to you."

Lin Yan shook his head, he was not very interested in this pen.

"Student, don't underestimate its origin. Have you seen the national emblem engraved on it? It symbolizes national honor. There are no more than [-] in the whole country. Are you sure you don't want it?"

so smart?

Lin Yan raised a vague smile on his lips, "Okay, I'll bet with you."

Zhou Mian glanced at the time, "Do you want me to time it for you?"

Lin Yan refused, "No need..."

Then he closed his eyes and recalled the formula he had just read in his mind.

In less than half a minute, he gave the answer, which was equal to half of π.

Zhou Mian looked at him in surprise. Although this question is not difficult, calculus is an absolutely difficult question for a student of his age, even a first grader, even a third grader.

Since he was looking at the calculus problem, Zhou Mian believed that he could solve this problem as long as it took time, but he didn't expect it to be so fast! !
