Xueba: The Knowledge I Teach, The Crit Is Returned

Of course, this moment is not only 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 also immediately notified the senior high school students of the whole school to start the live broadcast.

As for those students who have gone home for self-study, they make phone calls one by one to let them watch live learning at home.

No wonder these principals and leaders made a fuss.

The shock given to them by the last mock exam in Yangcheng No. 1 Middle School was too great.

If they hadn't seen it with their own eyes, they would not have believed that a small live-streaming studio could improve students' grades.

Isn't this bullshit!

But.... facts speak louder than words!

62 students with a score of 700 or above, 684 students with a score of 600 or above, Yangcheng No. 1 Middle School blocked all their mouths with their amazing results in the last mock test.

Moreover, in the period following the last mock test, they all personally verified this 'learning live room'.

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

This anchor is in stock!

This host is a genius!

What he teaches, the students can really understand easily, and can draw inferences from one case.

Moreover, they had never heard of the online public opinion in the past few days. When they saw that Gu Bai was able to push the "Zhou's Conjecture" a step further, they were even more shocked and speechless.

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

Therefore, the status of the learning live broadcast room in the hearts of the principals and college leaders of these colleges and universities is one more point.

Of course, Gu Bai not only informed the students of class 3 in Yangcheng.

He also posted a scarf on his scarf: "Learning live broadcast room, broadcast at 7 o'clock in the evening.

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

Although there are not many, although some of them were originally here to harass themselves, and most of them are no longer students, but Gu Bai doesn't care anymore.

In the last two days, he tried his best to let as many students of Daxia High School hear his class.

soon...

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

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

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

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

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

If you leave out the students in the third year of Yangcheng High School, there will be a full 4W+ of outside social personnel.

You know, this is only 10 minutes into the air.

"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.

Want to ask these social personnel really recognize their own live teaching ability?

The answer is: not approved.

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

And the most important point, they want to see this scholar who has advanced the 'Zhou's Conjecture' one step further.

Gu Bai then took his eyes back and stopped paying attention to the number of viewers in the live broadcast room.

Whether they are curious, or directed at Gu Bai's status as a scholar.

Gu Bai doesn't care, he... just concentrates on teaching, what other members of the society think is not important to him.

“Come on, first, first!!!”

"Is this the live broadcast room of Gu Bai Xueshen, come here because of his name! 35

"Yangcheng No. 1 Middle School Class 3 Registration!!!"

"I didn't expect so many high school seniors to watch Gu Bai Xueba's live broadcast room. Is it good?"

"Good good, very good, our Yangcheng No. 1 Middle School's overall score has increased by 200 points!!!"

"Really? 200 points? How long have you watched the live broadcast?"

"2 months, now estimates are higher, a month has passed. Last two days to sprint!!!"

"Uncle Ge goes to war, nothing will grow!!! Follow my slogan and shout."

"Uncle Ge went on an expedition, and nothing would grow!!!

In the live broadcast room, the bullet screen swiped across the screen.

Some of the audience members of the community have chatted with the senior high school students in the live broadcast room.

Gu Bai glanced at it and reminded him, "Stop chatting for seniors in high school, let's start teaching. As for the non-senior students, you can do whatever you want."

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

Like the last live broadcast, the questions this time are more difficult questions, in order to be published for this year's 'Uncle Ge'.

Title: [It is known that the function f(x)(x∈R) satisfies the following conditions; for any real number x1, x2 has? (x1−x2)2≤(x1−x2)[f(x1)−f(x2 )] and f(x1)−f(x2)≤lx1−x21, where ? is a constant greater than 0, let real numbers a0, a, b satisfy f(a0)=0 and b=a-?f(a). 】

[1: Prove? ≤ 1, and there is no b0=0, so that f(b0)=0;]

[2: Prove (b−a0)2≤(1−?2)(a-a0)2;]

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

Especially some people in the society...

Although most of them have gone through the college entrance examination, but... this has been a long time, (aibj) took a step back and said that even if they took the college entrance examination, they would not be able to do the subjects of this difficulty level.

"Fuck... this question is a bit difficult!!!99

"Come on, this is definitely the last question in the college entrance examination every year, but this is for those students who are admitted to Qingbei!!!"

"Uncle Ge is so cruel, what do you think you have forced the child into?"

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

Gu Bai didn't pay any attention to the barrage of social members in the live broadcast room.

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

"This kind of function problem is really difficult, but we should not be afraid, let alone challenge him..."

"Look, the title says that for any real number x1, x2? (x1−x2)2≤(x1−x2)[f(x1)−f(x2)] and f(x1)-f( x2)≤x1−x21, then can we start from x1, x2, which is also the key to opening the idea..."

"...We make x1, x2∈R, x1≠x2, then we can get: ?(x1−x2)2≤(x1−x2)[f(x1)−f(x2)],②(f( Is x1)-f(x2)≤1x1−x21) suddenly enlightened?

"Then we'll..."

While explaining, Gu Bai counted for the students on the manuscript paper...

After 3 months of lectures, Gu Bai's own teaching ability has also been greatly improved, coupled with the blessing of 40% of his systematic teaching comprehension and 40% of his ability to infer other things.

Soon, in the eyes of everyone, this question could not be completed at all, and most people thought it was a question prepared for the students of Qingbei.

It went so smoothly to the final result.

"From 3, [f(b)]2=[f(b)-f(a)+f(0)]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 I imagined?

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

When all the social personnel, watching the final result that was solved logically in the live broadcast room, they were stunned for a while.

Their eyes widened in disbelief, and immediately they turned their eyes to the steps on Gu Bai's manuscript in the live broadcast room and asked themselves:

Is this problem difficult?

It doesn't look simple.

However, why do you understand it all at once, and even feel very difficult from time to time!

And the most important thing is that they feel that when they encounter such a similar problem, they will not be able to solve it, but they will never be helpless, because they have the idea of ​​​​solving the problem.

Boom boom boom!!!

Immediately, the brains of all the audience 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 incredible!

Suddenly, the live broadcast room was full of barrages!

"Rely on, I understand, I understand it again and again."

"It's amazing, it's really amazing. This kind of topic that makes me have a headache when I look at it, I actually understand it so much that I don't even feel like I have anything to eat."

"Unbelievable, really unbelievable. That's... Is the charm of Gu Bai's seminary teaching? 99

"Understood, I finally understand why tens of thousands of students are so crazy to watch the live broadcast of Gu Bai Xue Shen. God, this special meow is the live broadcast room of Shenren. 35

"66666, makes me 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 getting admitted to a famous university!!!

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

They watched in shock at the live broadcast room called 'Learning Live', not knowing how to describe their inner thoughts.

But they know that they have been convinced!.
