Chapter 2452: irregular

Xu Yi preached a few words, which can explain profound things in a simple way, starting from the very small problems, leading to the grand, and all the insights made.
What's even more wonderful is that whenever someone asks a question, he breaks it at will.
Even though the outer world of Biyu Xue Palace is popular, all lecture halls are popular, talents are gathered, and various talented scholars are in the midst of it.
After three or two lessons, the preaching pavilion was completely overcrowded.
Xu Yi enjoyed this feeling very much. It was not the attention of everyone, but the collision of sparks of knowledge. While answering questions for others, there were always new sparks of thinking.
Day after day, year after year, Xu Yi gradually got used to this life.
Along with the preaching, the meritorious points in his lecture card gathered at a rapid speed, especially after experiencing a duel, the converging point of meritorious points reached a new climax.
That duel occurred in the fourth lecture of the preaching pavilion. Wang Moke overturned the preaching pavilion with a sword, and Xu Yi had to fight.
Wang Mo Ke, the corpse-slaying corpse, originally did not challenge Xu Yi's power, but he had the power to cause trouble. Of course, Xu Yi could choose to ask the council to intervene. Not conducive to preaching.
Wang Moke was so aware of this, he directly lifted off the top of the preaching pavilion. He knew that Xu Yi would definitely fight.
Xu Yi was indeed at war.
In fact, Xu Yi was not surprised by Wang Moke's appearance.
He knew very well that when he stepped on the shoulders of Kongming Island Big Five and jumped up, there would always be someone who wanted to step on his shoulder and fly.
Fame is a good thing, and everyone wants it.
Since Xu Yi dared to give a lecture at the preaching booth, he had long been prepared for the challenge.
Fighting with Wang Mo Ke, the influence is not small, he slashed Wang Mo Ke, and fully established the genius.
Lectures have become increasingly overwhelming ever since.
In the afternoon of this day, the preaching pavilion was absent, and Xu Yi talked about thirty-six plum blossoms.
A crystal screen emerged from the void, and Xu Yi waved his performance, one by one, and settled on the crystal screen.
When they talked about the wonderful things, everyone listened with enthusiasm. After the seventh number was finished, it was full of applause.
Xu Yi was waiting to be closed, and one of the fighters suddenly stood up. "Mr. Xu, I have a question. I don't know if he may be confused."
Xu Yidao, "You can share the problem with me. If you can solve it, the next time I answer with you, you can pay merit points. Now that the class is over, I have other things to do."
"And slow."
The client asked Xu Yi, "My question, the question alone, is of great value. If you ca n’t solve it, why do n’t you just listen to my question. If you can solve it, I will pay a black wish. Zhu, I can be more than a hundred meritorious deeds, but I ask Mr. Xu to read the question now and answer immediately. "
Xu Yi stared at the client. "You can't believe me?"
Dou Keke said, "Past lectures are not deceiving the world. I think Mr. Xu's age is not over a hundred. His accomplishments in mathematics are more profound than those monks who have accumulated hundreds of years. If there is someone behind Mr. Xu, the high-level theories and the difficult problems of analysis are all done by the person behind him, then I would ask Mr. Xu for advice, wouldn't it be wrong? "
Xu Yi secretly said, "This is to hit the scene."
While he was groaning, a whisper had been heard in the field, and then he was persuaded to take up the challenge.
Whether he is sincere about him, or he wants to try his true and false, he is happy to watch a lively event.
"That's it, your Excellency."
Xu Yi waved his hand and the crystal screen was reproduced.
In this matter, he has no room for retreat. Right now, he is in a good situation, and his meritorious points are accumulating fast. This good situation continues. It won't be long before he can master the board.
But all this has to be built on a good reputation.
In particular, he cannot let himself be infamous.
Still, public figures are not good.
But the influence of public figures is what he desperately needs.
If the matter before him is retired, he can immediately put his notoriety on himself. Regardless of true or false, the influence is always created.
What's more, Xu Yi has sufficient confidence in his accomplishments in the art of arithmetic.
Soon, Dou Ren dropped his own problem on the crystal screen. At the moment, there was a sound of gassing in the field, and then, the sound of disturbance began to rise.
"It's ridiculous, this is not the problem at all."
"I think Your Excellency is here to make trouble. Is there such a problem in the world?"
"How can such an irregular sphere find the volume area."
"How about the circle-cutting technique? How can the above coordinates be cut down, is it possible to find the result?"
"Irregular curves can't even list the equations. What should I ask for?"
"........."
Those who can listen to Xu Yi's thirty-six plum numbers in the preaching pavilion have profound accomplishments in counting.
At this moment, the fighters listed the topics, and they all couldn't understand, the problem was naturally serious.
Dou Ke looked at Xu Yi with a smile, "Your Excellency thought this was not a problem?"
What he listed on the crystal screen was a graphic question with two vertical and horizontal coordinates, clear scales, and an irregular ellipsoid in the coordinates. The requirement of the question was to find the area of ​​the irregular ellipsoid.
Xu Yi would like to say that this is not a problem, but a flash of spark flashed in his mind, and he subconsciously said, "This is indeed a problem, an excellent problem."
It turned out that Xu Yi's memories suddenly exploded, and he suddenly thought of the previous life.
In previous lives, he was not a good student and barely mixed undergraduate.
He didn't learn much about advanced mathematics at all, but he never learned it. He also knew that the area of ​​this irregular ellipsoid could be found in his previous life.
What is it, what is it, right, calculus, yes calculus ...
Speaking of this, Xu Yi in this world is definitely worthy of everyone's reputation.
However, he studied almost all the mathematical logic of the world, and the entire knowledge system was based on this ancient mathematical thought.
Even so, Xu Yi deeply understood the magnificence and vastness of mathematical knowledge.
In addition to technology, mathematics is also a kind of philosophical thought. In this world and previous lives, whoever has high mathematical skills, he does not praise the judgment, but he absolutely believes that the mathematical ideas he has received in this world are profound and transcendent.
"Mr. Xu, since you admit that this is a problem, let's solve it."
Dougyu smiled.
Xu Yidao, "This topic is a bit complicated. I need time to meditate ..."
The gangsters had to speak, interrupted by Xu Yi, "You don't have to worry about what rescuers I'm going to move, I'm meditating here. What restrictions do you need on the problem solving time?"
The duke wanted to say "of course", he suddenly noticed that all the people in Manting looked bad, apparently, they had made him intentionally to cause trouble.
Dou Keke said, "Anyway, I believe that Mr. Xu's ability will not be solved for several days."
