Chapter 048 Bachelor's Style

Don't make a lot of Noise, be quiet! This topic..."

The examiner looked a little embarrassed. Unexpectedly, he provoked the students to complain because of the question of pi. Although he is the chief examiner of these students, he does not dare to offend them easily. After all, one of them may be the big young master and young suzerain of a big force. In the face of the trouble of many students, the examiner not only wants to give up this question, but also does not want to give up. Giving up this question means that his examiner's question is bad and unrealistic, and obviously loses face. But if he doesn't give up this question, those students will not follow and make a lot of noise.

"Examer, if I can, I'll answer this question!" Just as the whole Yifu Square was indignant, a dirty and sloppy young man who looked like a beggar suddenly came out and stood in front of the crowd.

"You... OK, then you can answer this question!"

The examiner glanced at Hongxuan's dress and looked at the sloppy appearance. He couldn't help but feel a trace of contempt in his heart, but when he thought of the embarrassment he faced, he happily agreed for a moment. You should know that there is such a beggar who gives him a step down. Whether the other party can accurately rate the pi one, he can solve this problem in a just way. At that time, he will change another question. In this way, he will save face and the students will not make too much trouble.

"But I have another request. If the examiner agrees, I will do it. If you don't agree..." Hongxuan looked at the examiner meaningfully. He is not a kind-hearted person and took the initiative to step down the examiner. Today, he has his own purpose in doing this.

"What's the requirement, you say!" The examiner was a little hairy. He didn't expect that a beggar dared to make a request to himself. If it weren't for the right time, he would definitely find an opportunity to beat the beggar in front of him. It is secretly slandered that a beggar can also solve academic problems such as pi. If this is the case, why do people in mainland Kyushu still go to the university to study instead of being a beggar? In Yifu Square, all the students looked at Hongxuan with disdain, and most of them despised and despised the low-ranking beggars. Xiaoyang, who had just talked to Hongxuan, gently pulled Hongxuan's clothes and persuaded him in a low voice,

"Brother, are you really going up? Are you willing to be laughed at by everyone present?"

"Calculation pi, I want to take 5,000 medium-grade crystals."

He made a confident gesture to Xiaoyang. Hongxuan turned around and shouted to the examiner. Five thousand grade crystal is not a small amount. For Hongxuan, who is hungry now, it can be regarded as a small wealth. He can wait for this money to buy rice and put it into the pot.

"All work! As long as you calculate it, these 5,000 crystals are yours, and I will reward you with 5,000!"

Hearing the request of the sloppy beggar in front of him, the examiner immediately smiled like a flower, without thinking, and immediately released bold words and added a reward of 5,000 grade crystals. Looking up and down at Hongxuan, the examiner secretly sarcastically said, if you beggar can make the pi one accurate, what else do you want me to be the examiner? Why don't you be a beggar to be the examiner?

"You are the examiner. Once you say it, it's hard to catch up with you!"

With the cover of the dark and dirty sand on his face, Hongxuan smiled and did not give the examiner any opportunity to add any additional conditions. He flashed the students in the square and stepped into the speech in a few steps.

"Can beggars also calculate pi?"

"Is there any mistake? People like this also come to mess around."

"Go down, go down, it's embarrassing!"

As soon as Hongxuan came to the speech world, the whole Yifu Square immediately made a fuss. Everyone couldn't help cursing loudly when they saw Hongxuan's sloppy dress.

"Be quiet, I'm not a student of Hantian University, nor a tutor of Hantian University, let alone an amazing academic hermit master! I'm just a little beggar who wants to get 5,000 yuan. When he comes to this speech, to put it bluntly, it's a little man who wants to make a little money in a serious way. You have parents and predecessors, and family sects. You are born with no worries about food and clothing, and your future is bright. You are not as sloppy as me. I hope everyone can cooperate a little and calm down for the time being. When I get this 5,000 yuan crystal, I will leave immediately.

Hongxuan spoke very bluntly, and he was not afraid to offend these students with background and strength. After a few words, the whole Yifu Square calmed down in an instant and stared at him in consternation. No one could have thought of a beggar. In the face of hundreds of disciples, he was not only not nervous, but also had the courage to shout loudly.

"That's right."

Seeing that all the students were quiet, Hongxuan smiled, then turned around, picked up the spare brush on the speech, gently stained with ink, and walked towards a huge pair of grass-colored rice paper. His wrist shook, and a circle with a radius of about half a meter immediately appeared. The pen was stable, the pen was fast, and the stroke was light. The arm is round. After taking the pen, a circle that can't suddenly appear in the round circle!

"Good pen! Under the dance, a circle is suddenly displayed!"

"Is this beggar really good at writing?"

"What's the situation? This beggar draws a circle with one hand, which is actually more round than the tutor of the university?"

"It's just a circle. What's the use... playful guy."

"A person with strength will be a beggar, and this guy is not the kind of person who has real talent and learning."

After Hongxuan drew a circle, the whole quiet Yifu Square made a scene again. The students talked loudly one by one, and it was obvious that the two sides were arguing. At this moment, Xiaoyang clenched his fist and was secretly anxious for Hongxuan. Although the two knew each other for only a few minutes, his character still couldn't help worrying about Hongxuan. The examiner in the speechtan looked at Hongxuan with some surprise. He was a master. When Hongxuan took the pen, he had found some problems. No matter what the knowledge of the beggar in front of him was, at least his attainments in the brush were definitely far beyond ordinary people!

"Round, surrounded by curves, the curves are as smooth as silk, and there is no lag. In a circle, there are a series of things such as circumference, radius, diameter, radian and so on. In order to find the area of the circle, pi is a constant that cannot be ignored! Generally speaking, the pi is only the ratio of the circumference of the circle to the diameter. Of course, it is also equal to the ratio of the area of the circle to the square of the radius.

Holding a brush in his hand, Hongxuan began his problem-solving process. In solving the problem, he not only drew pictures, but also explained and explained. At this moment, he is like a knowledgeable tutor, tirelessly telling all knowledge. However, through his dress, a sloppy beggar actually held a brush and talked to a group of students. This scene was a little strange.

"Through the calculations of some predecessors in mainland Kyushu, you may have come to the conclusion that the pi is an irrational number, and it is an infinite non-cyclic irrational number. In daily life, pi is extremely important. For example, if a refiner wants to refine a sphere or polish a round surface, but he can't know the pi accurately, then the utensils he refines will be quite rough. Another example is an array mage. He wants to arrange a circular array. For various reasons, he needs the specific area of the circular array. However, the accuracy of the circumference is extremely weaker his calculation, and the power of the corresponding array will be much less.

"There are various methods for calculating pi, which can be said to be strange! In order to accurately pi, I propose three basic algorithms today!" Hongxuan held a brush in his hand. When he just wrote the word 'first kind' on the rice paper, the whole Yifu Square made another noise and looked at him with some surprise. As we all know, pi is extremely difficult to calculate, but the beggar in front of him dares to speak wildly and praises Haikou and proposes three ways to calculate pi. Ordinary bachelors, if they can come up with a way to calculate pi, it is extremely powerful. Now this unknown guy actually proposes three algorithms.

"The first calculation method is the most primitive and ancient. Although the idea is simple, the amount of calculation is quite complicated! But I have to say that it is still a very practical way. Hongxuan didn't pay attention to the students below. He picked up the brush, brushed it a few times, and drew a regular hexagon in the circle. The vertices of the regular hexagons fall evenly on the circumference, dividing a circle equally.

"The first way - circumcision. The so-called circumcision technique is to use a regular polygon to divide a circle evenly, and then calculate it. For example, at this moment in the circle, this regular hexagon has divided the circle equally, so on the basis of this regular hexagon, we add an isosceles triangle, so that a regular dodecagon is formed!"

After saying that, Hongxuan brushed a few times to draw a regular dodecagon. After finishing the pen, he turned around and asked the students in the square,

"Can you see the characteristics of this regular hexagon, regular dodecagon and this circle?"

"There is a fart characteristic. I saw you scribble with a brush somewhere, and there is no sign of calculating pi for half a day."

"That's right, if you don't understand, you have to pretend to understand! If you don't get out of the speech, that place is not easy for beggars to stand up.

"Don't make trouble, everyone. I have a little thought! The regular hexagon turns the circumference of the circle into six points, while the regular dodecagon turns the circumference of the circle into twelve points. If it is superimposed in turn and then calculated, the circumference of the circle can be cut unlimitedly and gradually shortened. When a limit is reached, it can even be considered that the segmented arc is a straight line! And the circle can be measured directly. With the ratio of circumference to diameter and the help of the extreme situation, this proportion is clearly displayed in front of us!"

Just as many students were making a fuss, a polite student suddenly patted his head, as if he had thought of something, and then talked about it endlessly. This student was none other than the first in the last grade of Hantian University. His literary comprehension almost surpassed many tutors in the college.
