Exclusive hot search

Chapter 51
There is a voting column in the upper right corner of the live broadcast room, allowing everyone to check their age range. This was specially added by Yan Fuguang.

According to the voting results, high school students and college students together accounted for more than 60%, so there are many audiences in this high math small class!

"Okay, back to the topic." Yan Fuguang put down the tablet and stopped paying attention to the message.

[Are you about to start? Come, come, I love learning, learning makes me happy! 】

[Can I be admitted to Hudan after studying? 】

Most of the audience were still joking, and didn't take words like "Aoyou" to heart at all. Even after knowing that Yan Fuguang was a student of Hudan, they thought she was only talking about high school life and her dreams for university.

But who knows, when Yan Fuguang opened his mouth...

"How many people are learning advanced mathematics? Or will learn advanced mathematics soon?"

The barrage was confusing for a while, but there are many majors in colleges that require advanced mathematics, and quite a few people answered "yes".

"Do you think there are any difficulties? I'll take a barrage and chat with you."

Now the audience is even more confused. Why did they start talking about advanced mathematics directly? Was the change so sudden?
So someone tentatively asked a score question.

Among the crowd joining in the fun of elementary school addition and subtraction, Yan Fuguang saw this at a glance.

"If f(x) is a [a, +∞) differentiable function and satisfies |f'(x)|≤N|f(x)|, f(a)=0. Where N is a constant greater than 0, Proof: f(x)=0."

Yan Fuguang nodded and said, "It's okay, let's do this."

As she said that, she turned around and wrote down the question on the whiteboard, without even thinking about it, she directly began to explain the proof process, and even thoughtfully gave three solutions.

The person who asked the question didn't know whether he understood it or not, but there were really people who learned advanced mathematics in the barrage who listened carefully, and then typed wildly and shouted in shock.

[No bragging or blackmail, very well spoken! 】

[It’s well said, especially the third solution, it’s really ingenious. 】

[Are there so many bosses?Liberal arts students trembling]

【I'm not even worthy of trembling as a high school student, I'm simply out of place】

[Are junior high school students unworthy of watching, I'm a little panicked]

[Junior high school students don't go to study yet?What to watch live】

[I can't understand a word, but I don't understand it]

It is said that there are another 40% of the audience who either do not understand at all, or their school days have long since ended, but miraculously, the number of online people has not decreased, on the contrary there has been a slight increase.

The main reason is that students all over the Internet began to promote it spontaneously in class groups.

"The super big beauty who became popular overnight is actually a top student in Shanghai and she also broadcasts a live broadcast to talk about high math problems." Such a long title is full of key points, which is simply eye-catching.

Those who are far away from the campus are reluctant to leave even if they don’t understand it. After all, this kind of scene is too rare to see. Isn’t this more beautiful than those howling live broadcasts of demons dancing wildly?

【If my math teacher is like Yan Fuguang, I can't fail in math! 】

【Is there a possibility that you are just stupid and can't learn】

[If there was such a teacher back then, I should be in Wudaokou Vocational and Technical College now, not Lanxiang Technical School]

[There is a sinful urge to cut open Yan Fuguang's head to study the structure, isn't he a freshman yet, why is he more familiar with me than me! 】

【You are not alone! 】

[The person who said just now that Yan Fuguang knows high mathematics and eats flying upside down, please tell me the room number of the live broadcast room, I will give you ten planes, and you will eat it hard! 】

There are people who say anything for a while, and the barrage floats faster and faster.

[No one really believes it, just find someone to ask the question, Yan Fuguang reads the answer, can this also be boasted? 】

[Xingchen is still amazing, first he used tricks to get the endorsement, and now he tricks the audience, is the brokerage company's way of flattering people already so outrageous? 】

【Mathematics today, physics next time, what kind of artist are you so awesome, you should have a place in the Nobel Prize! 】

Yan Fuguang, who did not follow the usual path, provided Heizi with a new idea.

However, the number of sunspots cannot compare with the silent majority, not to mention that no one wants to be silent now, and they are all outputting.

[For me, assume that A and B are both mn matrices, if there is an nn matrix P, Q makes AP=B, BQ=A, prove: (1) There is an nn matrix K such that P+(PQEn)K is an invertible matrix;( 2) There is an nn matrix C such that AC=B.]

[Known A, B∈Rnn, and satisfy rank(ABA)=rankB. Proof: ABBA.]

One topic after another, maybe most people just want to join in the fun, but the enthusiasm of the audience is still far beyond Mo Yun's imagination.

Originally, I thought that it would be lucky not to overturn this kind of topic, but I didn't expect that Yan Fuguang could answer any questions.

Later, even if the audience listened to the scriptures, they didn't want to leave. Many people hung up in the live broadcast room just to see if Yan Fuguang would be stumped.

In the end, the sunspots couldn't hold on any longer, no matter how bad they were, Yan Fuguang could slap them in the face on the spot, the kind of forehand and backhand education.

In the end, the two-hour live broadcast was dragged to two and a half hours before it ended.

"Okay, that's all for today, see you next month." Yan Fuguang waved at the camera.

【Come on, let’s talk again~】

[How many cards!Don't leave us! 】

[Sister is fine if she is tired and doesn't talk, just turn on the camera, I can't bear to part with your flourishing beauty]

As soon as Yan Fuguang said he wanted to leave, the barrage was all acting like a baby.

"It's useless to act like a baby, I have a heart of stone." Yan Fuguang said with a smile.

[It's not hard-hearted, you obviously live broadcasted for half an hour more for us, mother doesn't allow you to say that about yourself! 】

【Yan Fuguang, mom loves you! 】

[Yue, male mother, hurry up and get out! 】

"Okay, I really have to go. I will notify you in advance of the next live broadcast. Goodbye everyone!" Yan Fuguang waved goodbye again.

The picture in the live broadcast room was interrupted suddenly, but the popularity on Weibo was in full swing.

Yan Fuguang's hot searches before were all during the period of "Survival on a Deserted Island". Later, the spokesperson of Lightning's official announcement also exploded once, but this time the entry of #维复光湖旦# directly parachuted to the top of the list.

The first few posts were all screen recordings in the live broadcast room, and someone made a guide post to collect all the questions that Yan Fuguang talked about.

Weibo has much more room to play than barrage.

[I thought Yan Fuguang's performance on the desert island was already at his limit, but I didn't expect it to be just an appetizer. 】

[Yan Fuguang is really a freshman? 】

[So people participated in a variety show after the college entrance examination to relax, and then became famous inadvertently. Can you believe that? ! 】

[I've seen too many fake academic masters in the entertainment industry, and now I'm finally here for the real thing! 】

[I am a senior in the Department of Mathematics. To be honest, a few questions are already in the scope of the postgraduate entrance examination. It is hard to imagine that she is just a freshman who has not reported yet. 】

[Seriously upstairs? 】

[I'm from Hudan, just now our class group has gone crazy, and the school forums are all posted by Yan Fuguang. I can see a real person in September, so excited! 】

[Okay, okay, I can see that you are very excited, don't show off here, okay, be careful of being struck by lightning]

[This kind of top beauty + top student must have been a famous figure in high school, why didn't her classmates come forward to claim it? 】

[A huge reward is offered, is there any former classmate who will come out and talk about it, I really want to know what Yan Fuguang was like in high school! 】
