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

At this time, Yangcheng 3 Middle School, Yangcheng 12 Middle School, Yangcheng Hongqi Middle School….

When they heard that Gu Bai was going to start live teaching, they also notified the senior students of the whole school to start live streaming as soon as possible.

As for those students who have gone home to study on their own, they are called one by one and asked them to watch live learning at home.

And don’t blame these principals, leaders for making a fuss.

It was really the shock given to them by the last mock exam of Yangcheng No. 1 Middle School, which was too great.

If they hadn’t seen it with their own eyes, they wouldn’t want to believe that a small live studio would improve students’ grades.

Isn’t this a rip-off!

But…. Actions speak louder than words!

62 students with more than 700 points, students with more than 684,600 points, Yangcheng No. 1 Middle School blocked all their mouths with amazing results of the last mock test.

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

This streamer is in stock!

This anchor is a god man!

What he teaches, students can really understand and draw inferences. of speechless.

It turns out that this anchor is not only good at teaching, he is also a super student!

Therefore, the status of the learning live broadcast room in the hearts of these college presidents and college leaders has been a point higher.

Of course, Gu 360 Bai didn’t just notify the students of Yangcheng Class 3.

He also posted a bib on his neck: “Study live broadcast room, start broadcasting at 7 o’clock in the evening.” ”

Originally, Gu Bai had no publicity means, no way to publicize to attract more people, but now his bib also has 50w fans.

Although there are not many, although some of them originally came to hack themselves, most of them are not students, but Gu Bai does not care anymore.

In the last two days, he tried to let as many senior students as possible hear his class.

Soon…

It was 7 o’clock in the evening.

Gu Bai also opened the live broadcast room on time…

Suddenly, Gu Bai’s live broadcast room poured into a large number of students and viewers….

1000,2000…. 10000….30000…..60000…

In just ten minutes, Gu Bai saw that the audience in the live broadcast room in his upper right corner had reached 6w+

If you throw away those students in the third year of Yangcheng High School, there are enough 4w+ for external social personnel

You know, this is only 10 minutes after the broadcast.

“It seems that the attraction of Zhou’s conjecture is quite large.”

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

Do these social workers really recognize their ability to teach live streaming?

The answer is: no.

Most of them said that the reason for coming here is nothing more than because of the lively Internet public opinion in the past few days.

Gu Bai then withdrew his gaze and no longer cared about the number of viewers in the live broadcast room.

They are curious or not, and they are also interested in Gu Bai’s identity as a scholar.

Gu Bai didn’t care, he… Just concentrate on teaching, what other social workers think, it doesn’t matter to him.

“Here it comes, the first first !!!”

“Is this the live broadcast room of Gu Bai Xueshen, admiring, admiring!”

“Yangcheng No. 1 Middle School Class 3 Registration !!!”

“I didn’t expect that Gu Bai Xueba’s live broadcast room had so many senior students watching, is it good???

“Good, good, good, very good, our overall score of Yangcheng No. 1 Middle School has increased by 200 points!!!”

“Really fake? 200 points? How long have you been watching the live broadcast? ”

“Two months, now the estimate is higher, one month has passed. The last two days are a sprint!!! ”

“Uncle Ge went on a campaign, and he didn’t give birth to a single grass!!! Follow my slogan, shout. ”

“Uncle Ge went on a campaign, and he didn’t give birth to !!! grass”

“……”

In the live broadcast room, the barrage was full of screens.

Some viewers of social personnel and senior students in the live broadcast room have already chatted with each other.

Gu Bai glanced at it and reminded: “Don’t chat with the students in the third year of high school, let’s start teaching below.” As for non-senior students, you feel free. ”

After speaking, Gu Bai put the prepared topic in the live broadcast room.

Title: [The function f(x)(xR) is known to meet the following conditions; For any real number x1, x2? (x1-x2)2(x1-x2)f(x1)-f(x2) and f(x1)-f(x2)x1-x2, where ? is a constant greater than 0 , and let the real numbers a0,a,b satisfy f(a0)0 and ba-f(a). 】

[1: Proof −1, and there is no b0a0 such that f(b0)0; 】

[2: Proof (b-a0)2(1-?2)(a-a0)2; 】

When Gu Bai put the prepared topic in the live broadcast room, everyone was dumbfounded.

Especially some people in society … (Read violent novels, just go to Feilu Fiction Network!) )

Although most of them have experienced the college entrance examination, but… This is a long time ago (AHFA), and even if they take the college entrance examination, they can’t do this difficult subject.

“Groove… It’s a bit difficult!!! ”

“Lean, this is definitely the last finale question of the college entrance examination every year, but this is a !!! for those students who take the Qingbei exam.”

“Uncle Ge is really ruthless, look at what you have forced the child to look like?”

“Poor children, poor high school juniors, most of them are not yet adults!”

“……”

For the barrage ridiculed by the members of the society in the live broadcast room, Gu Bai did not deal with it again.

Looking at the topic and beginning to analyze, he explained it to all the students of Yangcheng High School.

“This kind of function topic is indeed more difficult, but we should not be afraid, let alone dare not challenge him…”

“You see, the title says that there are any real numbers x1 and x2? (x1-x2)2(x1-x2)f(x1)-f(x2) and f(x1)-f(x2)x1-x2, then can we start from x1, x2, which is also the key to opening ideas…”

“… If we let x1,x2Rxlx2,then we get: ?(x1-x2)2(x1-x2)f(x1)-f(x2),(f(x1)-f(x2)x1-x2)? ”

“After that, we’ll then…”

Gu Bai explained while calculating to the students on the manuscript paper…

After 3 months of teaching and explanation, Gu Bai’s own teaching ability has also been greatly improved, coupled with the blessing of 40% of systematic teaching understanding and 40% of the ability to draw inferences.

Soon, this question, which was simply impossible to complete in the eyes of everyone, was considered by most people to be prepared for students in Qingbei.

It was logical to come to the final result.

“By knowing 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 is solved, is it not as difficult as imagined?”

Gu Bai’s faint words came from the live broadcast room.

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

Their eyes widened in disbelief, and immediately they looked at the steps on the white manuscript paper in the live broadcast room and couldn’t help but ask themselves:

Is this difficult?

It doesn’t seem simple.

But why do you understand it all at once, and even feel that it is difficult from time to time!

And most importantly, I feel that I will not solve such a similar problem, but I will definitely not be helpless, because they have ideas for solving the problem.

Boom!!

Suddenly, the brains of all the viewers who listened to Gu Bai’s live broadcast for the first time set off a huge wave, and their faces showed a touch of shock.

Shocking, but also in the incredible!

Suddenly, the live broadcast room was full of barrages!

“Leaning on, understood, understood.”

“God, really God. This kind of topic that I have a headache when I look at it, I actually understand it, and I even feel that I haven’t eaten anything yet. ”

“Unbelievable, really unbelievable. This is… What is the charm of Gu Bai Xueshen teaching? ”

“Understood, I finally understood why tens of thousands of students were so crazy to watch Bai Xueshen’s live broadcast. God, this special meow is the god-man live broadcast room. ”

“66666, I want to go back to the college entrance examination again!”

“The same feeling, I feel that there is absolutely no problem in studying with Gu Bai Xueba, and being admitted to a prestigious university!!!”

At this moment, all the social meeting personnel in the live broadcast room, and some people who listened to Gu Bai’s live broadcast for the first time were stunned.

But they know that they have been convinced!.
