Xueba: The knowledge I teach, critical hits are returned

Of course, this moment is not just Yangcheng No. 1 Middle School.

At this time, Yangcheng No. 3 Middle School, Yangcheng No. 12 Middle School, Yangcheng Hongqi Middle School....

When they heard that Gu Bai was going to start live teaching, they immediately notified all the senior high school students in the school to start live teaching. As for those students who had already gone home to study, they were called one by one and asked to watch the live broadcast at home.

It's no wonder that these principals and leaders made a fuss.

It was really because the last mock exam of Yangcheng No. 1 Middle School gave them such a big shock.

If they hadn't seen it with their own eyes, they would not have believed that a small live broadcast room for learning could improve students' grades.

Isn't this bullshit!

But....Facts speak louder than words!

62 students scored above 700, and 684 students scored above 600. Yangcheng No. 1 Middle School shut up all of them with the amazing results of the last mock exam.

From the surprised and excited eyes of the students, the principals and leaders of these high schools completely believed it.

This anchor has the goods!

This anchor is a god!

What he teaches, students can really understand it simply, and can draw inferences from one example. Speechless.

It turns out that this anchor is not only a good teacher, but also a super academic master!

Therefore, the status of the learning live broadcast room in the hearts of these college principals and school leaders has increased by one point.

Of course, Gu 360 Bai did not only notify the students of Yangcheng Class 3.

He also posted a Weibo on his Weibo:"Learning live broadcast room, start broadcasting at 7 pm."

Originally, Gu Bai had no means of publicity and no way to promote and attract more people, but now his Weibo has 50w fans.

Although not many, although some of them were originally here to black him, and most of them are not students anymore, but Gu Bai doesn't care.

In the last two days, he tried his best to let more Daxia senior high school students hear his class. soon...

The time came to 7 o'clock in the evening.

Gu Bai also opened the live broadcast room on time....

Suddenly, a large number of students and viewers flooded into Gu Bai's live broadcast room.....

1000, 2000....10000....30000.....60000...

In just ten minutes, Gu Bai saw that the audience in his live broadcast room in the upper right corner had reached 60,000+.

If we exclude those students in Yangcheng High School, there were also 40,000+ people from the outside world.

You know, this was only 10 minutes after the broadcast started.

"It seems that Zhou's conjecture is quite attractive."

Gu Bai smiled and muttered to himself. Of course, he knew why there were so many viewers in the live broadcast room.

Do these people really recognize his ability to teach live?

The answer is: no.

Most of them said that the reason they came here was nothing more than to join in the fun of the online public opinion in the past few days.

Gu Bai then retracted his gaze and no longer paid attention to the number of viewers in the live broadcast room.

Whether they were curious or attracted by Gu Bai's academic status.

Gu Bai didn't care. He...He just needs to concentrate on teaching. It doesn't matter what other people think.

"Here it comes, first first!!!"

"Is this the live broadcast room of the academic master Gu Bai? People come here because of his reputation! They come here because of his reputation!"

"Class 3 of Yangcheng No.1 Middle School reports!!!"

"I didn’t expect that there would be so many senior high school students watching Gu Bai’s live broadcast room. Is he good at speaking???"

"Very good, very good, the overall score of our Yangcheng No. 1 Middle School has increased by 200 points!!!"

"Is this true? 200 points? How long did you watch the live broadcast?"

"2 months, now the estimate is higher, a month has passed. The last two days are for a sprint!!!"

"When Uncle Ge goes to war, not a blade of grass will grow!!! Follow my slogan and shout"

"When Mr. Ge goes to war, not a blade of grass will grow!!!"

"......"

In the live broadcast room, the barrage of comments filled the screen.

Some social viewers had already started chatting with the senior high school students in the live broadcast room.

Gu Bai glanced at them and reminded them:"Senior high school students, please stop chatting. The class will begin. As for those who are not senior high school students, you can do whatever you want."

After that, Gu Bai put the prepared questions in the live broadcast room.

Question: [It is known that the function f(x)(xR) satisfies the following conditions; for any real numbers x1, x2, there are ?(x1-x2)2(x1-x2)f(x1)-f(x2) and f(x1)-f(x2)x1-x2, where ? is a constant greater than 0. Suppose real numbers a0, a, b satisfy f(a0)0 and ba-?f(a)】

【1: Prove that ?1, and there does not exist b0a0 such that f(b0) 0;】

【2: Prove that (b-a0)2(1-?2)(a-a0)2;]

When Gu Bai put the prepared question into the live broadcast room, everyone was stunned.

Especially some people in society...(To read the exciting novels, go to Feilu Novel Network!)

Although most of them have experienced the college entrance examination,...This has been a long time coming (ahfa). Even if they took the college entrance examination, they would not be able to answer questions of this level of difficulty.

"WTF...This question is a bit difficult!!!"

"Damn it, this is definitely the last question of the college entrance examination every year, but it is prepared for those students who are taking the entrance exams for Peking University and Tsinghua University!!!"

"Uncle Ge is so cruel. Look at what he has done to the child."

"Poor children, poor high school seniors, most of them are not yet adults!"

"......"

Gu Bai ignored the comments from the social members in the live broadcast room.

He analyzed the question and explained it to all the senior high school students in Yangcheng.

"This kind of function question is indeed quite difficult, but we should not be afraid, let alone dare to challenge it...."

"You see, the question says that for any real number x1, x2, there are? (x1-x2)2(x1-x2)f(x1)-f(x2) and f(x1)-f(x2)x1-x2, then can we start from x1, x2? This is also the key to open up the idea...."

"...We let x1,x2Rxlx2, then we can get: ?(x1-x2)2(x1-x2)f(x1)-f(x2), (f(x1)-f(x2)x1-x2) Doesn’t it make sense?"

"After that we will..."

Gu Bai explained while calculating for the students on the manuscript paper....

After three months of teaching, Gu Bai's teaching ability has also improved greatly, and the system's teaching has helped him improve his comprehension by 40% and his ability to draw inferences by 40%.

Soon, this question that everyone thought was impossible to solve, which most people thought was prepared for students taking the entrance exams for Peking University and Tsinghua University, actually came to the final result.

"From the above we know that f(b)2f(b)-f(a)+f(a0)2....."

"f(b)2(1-?2)f(a)2;(b-a0)2(1-?2)(a-a0)2"

"This problem has been solved. Isn't it not as difficult as imagined?"

Gu Bai's indifferent words came from the live broadcast room.

When all the social personnel looked at the final result that was solved naturally in the live broadcast room, they were stunned for a moment.

They widened their eyes in disbelief, and immediately they looked at the steps on Gu Bai's manuscript paper in the live broadcast room and asked themselves:

Is this problem difficult?

It doesn't look simple.

But why did they understand it all at once, and even felt very strenuous from time to time!

And the most important thing is that they feel that if they encounter similar questions like this, they will not be able to solve them, but they will definitely not be helpless, because they have ideas to solve the problems.

Boom boom boom!!

Suddenly, all the audiences who listened to Gu Bai's live broadcast for the first time had huge waves in their brains, and their faces showed a touch of shock.

Shocking, it is also too incredible!

Suddenly, the live broadcast room was full of bullet screens!

"Damn it, I understand it, I understand it once"

"Amazing, really amazing. This kind of question gives me a headache just by looking at it, but I actually understood it, and I even felt like I had nothing to eat."

"Unbelievable, really unbelievable. This is...Is that the charm of Gu Bai’s lectures?"

"I understand. I finally understand why tens of thousands of students are so crazy about watching Bai Xueshen's live broadcast. God, this is the live broadcast room of a god."

"66666, it makes me want to go back and take the college entrance examination again!"

"The same feeling, feeling that following Gu Bai's lectures and studying, there is absolutely no problem in getting into a prestigious university!!!"

At this moment, all the social members in the live broadcast room, some of whom were listening to Gu Bai's live broadcast for the first time, were stunned. But they knew that they had been convinced!.
