Chapter 775

Since the construction will take time, the matter will come to an end first.

Shu Cheng spent all day reading the code and drilling the library, and then he was asked to make complaints about the boring program.

This interview program is a very popular program in Z country at present. The host Yu Jie's hosting style is serious and funny. He will tease the guests from time to time, but it will not be too much. Therefore, it is deeply loved by the audience.

"Yu Jie has promised to record the interview."

"When?"

"About tomorrow morning, I'll go to Tsinghua University to interview you in person."

"Yo Ho, am I so good?"

"... according to Yu Jie's personality, he should come early. Take you by surprise and pay attention to your image."

Shu Cheng frowned: "... When is my image bad?"

Shen He: "if you don't comb your hair in the morning, it's like a chicken nest."

"Nonsense." Shu Cheng rubbed his hair. "I didn't get up in the morning of my holiday."

Shen He: "

"And I have a daughter-in-law for combing my hair?"

Shen He: "..." ha ha.

"I slept with him, and he relied on me!"

Shen He: "... Do you feel my silence??

"Forget it, you don't understand when you talk to a single dog like you. You can't understand this pain. It's really annoying."

Shen He: "!!!" Shu Cheng, you have a daughter-in-law. You are six!

……

However, at this time, Yu Jie has investigated Shu Cheng's schedule for today.

Standing in front of the camera lens, he made a "OK" gesture to the staff and adjusted the state. He said, "Hello, everyone. This is Tsinghua University. This time we should interview everyone who should have guessed who it is."

"Yes, it's young Shu Cheng who won the title of Queen of film, the king, the father of Harry Potter, the world-renowned best-selling author, and the king of online literature!"

Yu Jie's figure standing at the gate of Tsinghua University attracted many Tsinghua students to stop and watch. Yu Jie's interview has always been very hot, and many people know her. When you see this posture, you can know that you must have gone to interview Shu Cheng.

At this time, Shu Cheng was bored reading in the library.

From time to time, girls will look at Shu Cheng's direction, and sometimes ask Shu Cheng for explanation with a high number exercise.

"This problem should be done like this. Solution: Let f (x) = X ³ − 3ax + A, it is obvious that f (x) is continuous and differentiable in the interval [0,1], and f '(x) = 3 (x + √ a) (x - √ a).

(1) When a ≥ 1, f (x) has no stagnation point in the interval (0,1), and f '(x) 0; f (1) = 1-2a < 0

（2）……

... 
 when f (√ a) = a (1-2 √ a) ＜ 0 and f (1) = 1-2a ≤ 0, i.e. 12 ≤ a < 1, f (x) has only one zero point in the interval (0, 1),

At this time, the original equation has only one real root in the interval (0, 1). "Shu Cheng explained to the girls slowly and patiently. He didn't dislike the simplicity of the topic at all.

Just then, the cell phone rang.

"Sorry, I'll take a call."

"It's all right. Take it."

Shu Cheng stepped aside and pressed to answer the phone. Shen He's voice came from the opposite side.

"The hostess of the fairy sword and chivalry has been found."

"Oh, really? I want to see her," Shu Cheng said.

When the girl saw Shu Cheng answer the phone, she looked at the book Shu Cheng was reading.
