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

Shu Cheng spends all day studying in the library, codewords, and complaining about being bored, Shen He finds him to record a talk show.

This talk show is currently a very popular show in Country Z. The host Yu Jie's hosting style is serious but also humorous. He will spoof the guests from time to time, but it will not be too much, so it is deeply loved by the audience.

"Yu Jie's interview recording has been agreed."

"when?"

"About tomorrow morning, I will personally rush to Tsinghua University to interview you."

"Yo ho, am I such a bully??"

"...According to Yu Jie's personality, it should come very early, and you will be caught off guard. Pay attention to your image."

Shu Cheng frowned: "...Which day will my image be bad?"

Shen He: "If you don't comb your hair in the morning, it's as messy as a chicken coop."

"Nonsense." Shu Cheng rubbed his hair, "I didn't get up in the morning even though I was on holiday."

Shen He: "..."

"And combing hair, don't I have a wife??"

Shen He: "..." Hehehe.

"I've already put him to sleep, I'm his only support!!"

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

"Forget it, I told you a single dog, you don't understand, this kind of suffering, you can't understand, it's really annoying."

Shen He: "!!!" Shu Cheng, you have a wife and you are very six!

...

However, at this moment, Yu Jie had already investigated Shu Cheng's schedule for today.

Standing in front of the camera, Yu Jie made an "OK" gesture to the staff, adjusted her status, and said, "Hi everyone, this is Tsinghua University. Everyone we are going to interview this time should have guessed Who is it?"

"Yes, it is Shu Cheng, the young man who has won the crown of best actress and best actress alone, the father of the internationally renowned best-selling author Harry Potter, the king, and the king of online literature, An Zhiruosu!"

The figure of Yu Jie standing at the gate of Tsinghua University attracted many Tsinghua students to stop and watch. Yu Jie's interviews have always been very popular, and there are many people who know her. Seeing this posture, everyone knows that she must be interviewing Shu Cheng of.

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

From time to time, girls would look in Shu Cheng's direction, and sometimes they would hold a book of advanced math exercises and ask Shu Cheng for an explanation.

"This question should be done like this. Solution: Let f(x)=x3? 3ax+ a, obviously f(x) is continuous and derivable on 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 at this time f'(x)\u003c0, and f(0)=a\u003e0;, f(1 )=1- 2a\u003c0

(2)……

...?When f (√a)=a(1-2 √a)\u003c0, and f(1)=1- 2a≤0, that is, 1/2≤a\u003c1, f(x) is in the interval ( 0, 1) there is only one zero point,

At this time, the original equation has only one real root in the interval (0, 1). "Shu Cheng spoke slowly and patiently explained to the girl, not at all disliking the question for being too simple.

At this moment, the phone rang.

"Sorry, I have a call."

"It's okay, you can take it."

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

"The heroine of "Legend of Sword and Fairy" has been found."

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

When the girl saw Shu Cheng answering the phone, she took a look at the book Shu Cheng was reading when she was bored.
