Mythical Version of the Three Kingdoms

After Xu Yue finished speaking, he was ready to run. It's not that he can't calculate it. He has the idea and the method is correct. But these days, you have to calculate the precise pi by yourself, especially when it is used to calculate the radius of the earth. How accurate is it? The degree must at least reach an integer, and conversely, the pi must be calculated to at least seven or eight digits. It slips away, it slips away, triangles are easy to calculate, but pi is terrible.

Li You grabbed Xu Yue and said something. At this time, Li You really felt that Xu Yue was quite useful. After reading the question, nothing could be left in his mind. Xu Yue just thought about it. Knowing how to calculate, Li You is satisfied with this.

"How is this calculated?" Li You grabbed Xu Yue and asked. He was really curious about this.

"What's the point of this? Just rely on the change in degree to solve the triangle, but what is actually calculated is the circumference. After the calculation, the radius is calculated based on pi. The only trouble is that pi is difficult to calculate. At least this must be calculated. Seven or eight digits, I don’t want to cut a circle, it’s too uncomfortable to calculate it by force, such pure numbers are meaningless, I like the mathematical rules in it,” Xu Yue said very dissatisfied, he has no interest in calculation. , Zhao Shuang likes this kind of thing, what he likes is mathematical logic.

Although they are both mathematicians, Xu Yue actually pursues mathematical logic and studies the laws of mathematics. Therefore, his spiritual talent allows him to forcibly write a usable operating system, because what is needed for things like machine code is logic. and rules, and Zhao Shuang uses pure numbers, so if Zhao Shuang is now asked to calculate pi, Zhao Shuang can just calculate the tens of thousands of digits without any problem.

But if Xu Yue is asked to calculate this, to be honest, Xu Yue can only calculate it slowly using the secant method. Unless he takes the time to make a special calculation program, Xu Yue will feel uncomfortable if he is asked to calculate it by himself.

To put it bluntly, after the sixth or seventh digit of pi, the normal calculation method is a bit too difficult. Although Xu Yue can also calculate it, as someone who knows the radius of the earth, he knows very well how to calculate it in writing. The process is just to take a more accurate value of pi to ensure the accuracy of the integer part of the earth's radius value. The circle cutting method only needs to cut the edges to 24576 polygons...

After all, Chen Xi's question has already made it very clear. If you only know that the interior angles intersecting parallel lines are equal, then you have to calculate everything else by yourself, which is very life-threatening.

Xu Yue quickly explained to Li You on a piece of paper how to calculate the radius of the earth based on such a piece of information. Li You was extremely silent. As a spiritual gift holder and one of the best, how much consciousness did Li You have? When it comes to mathematics, you just don’t know how to do it.

"Actually, the difficulty of this question is not to calculate the circumference, but the radius." Xu Yue said with some regret, "The first half of the circumference is considered a scoring question."

Xu Yue said this, and Jiang Wan on the side put his hand on his forehead. Is this actually considered as giving points? Ah, this can be regarded as a score question.

"Absolutely. It's indeed a scoring question." Chen Xi nodded, "The difficulty of this question is actually to find the radius, because the earth is very big, and when you calculate, the minimum requirement is to be accurate to single digits, and the existing With this huge circumference value, the three-dimensional diameter can only be accurate to the thousands.”

Fazheng on the side twitched when he heard this. Can this be considered a point question? If I remember correctly, my grandfather and I learned arithmetic very well when I was a child. The problem is that I have never seen such a perverted question since I was a child. Are you kidding? This is a question for free?

"It's a sub-question. There are at least more than 300 people in the Central Plains who can solve this problem after being informed of the pi ratio." Xu Yue thought for a while and said, "Anyway, most of the families who engage in astronomical phenomena can do it. This, the method used by the Gan and Shi family when they first calculated the circumference of the earth was actually similar to this. They didn't realize it for a while after reading the question at most, but they figured it out after thinking about it. "

"The real difficulty is actually to directly calculate pi without prefix, and calculate the radius accurate to single digits. How many times does this need to be calculated at least?" Chen Xi looked at Xu Yue and asked, he didn't give pi in this question, and even if he knew it Pi, the existing normal pi is not enough to calculate a single-digit radius, at least six or seven decimal places.

"It takes one calculation to cut a side. If there are no mistakes in the whole process, it will take about 90,000 times to calculate the length of the triangle's sides and the same number of times to calculate the perimeter. It's my estimate. If I do this question, I'm afraid I won't be able to do it within the given time. I can't even calculate it." Xu Yue thought about it and said, the exam time is too short, and there are more than 90,000 trigonometric function calculations plus perimeter calculations. I'm afraid his calculation ability is really not good.

There is no way, the further you calculate, the more decimal points you have, and you can't take fuzzy values. The actual calculated data may be in the millions. Xu Yue doesn't want to participate in this kind of cheating game.

"I estimate that Zhao Shuang is the only one in the entire Central Plains who can solve this question to Chen Hou's satisfaction within the exam time, and he also has to use his mental talent." Xu Yue said angrily.

Do you think the difficulty is to calculate the triangle and its perimeter?

That's just an introduction. The real difficulty is that after you know the super large circumference, you can back-calculate the pi without pi!

"Indeed, as long as it doesn't count to kilometers, in this case, it won't be very difficult to four decimal places." Chen Xi thought for a while and said.

Xu Yue sneered when he heard this and took a gamble. Even those who can calculate will give up directly when they see this question. Only guys like Zhao Shuang can do this kind of question. This is really a pure competition for calculation power. His uncle's , if you want to be accurate to the millimeter, you need at least a dozen digits.

According to the unoptimized hard calculation method of the secant method, every additional digit will directly increase the index. With more than a dozen digits, Xu Yue suspected that what Chen Xi was looking for was not a math guy, but a computer.

"In short, the difficulty of this question does not lie in what you think is difficult, but in how to get the value." Xu Yue said angrily, "If you really want to make it difficult, the difficulty will be so high that it will explode."

Human supercomputers have calculated pi for more than a hundred days, and they can still continue to calculate. The questions are just to screen the geniuses among ordinary people. Those who truly realize the problem are the ones Chen Xi wants.

"Did you run out of numbers?" Xu Yue made treacherous remarks to Chen Xi, not taking Chen Hou's majesty seriously at all.

"You know, why don't you hurry up and make it?" Chen Xi didn't care about Xu Yue's tone at all, because he really lacked super calculation, even the kind that was not very strong, it would be fine, and it would not be a loss for other calculations.

Xu Yue had nothing to say and ran away. He could no longer stay in such a cowardly place.

Fazheng, Jiang Wan and others fell into isolation when they saw the exchange between Chen Xi and Xu Yue. They estimated that they would never make such outrageous remarks about themselves being good at mathematics again. Good at mathematics? Hahaha, the concept of being good at mathematics does not exist in the human world. In fact, the more you know about mathematics, the smaller you will feel!

"Then let's take this question as the last big question in arithmetic. How accurate is it?" Li You turned to look at Chen Xi and asked after Xu Yue ran away.

"It's just a joke. How could I be so bad? Of course it should be accurate to three decimal places, just a few kilometers." Chen Xi said with a smile. He is not an animal, how could he be as perverted as Xu Yue thought? .

Li You glanced at Chen Xi and was too lazy to discuss the matter with Chen Xi.

"Do you have anything else? If not, I'll run away first." After Chen Xi answered Li You's question, he looked at the sky, considered the problems Zhou Yu was currently facing, and decided to go home and sleep. Can you help Zhou Yu? After all, he tried his best before, but the situation was not very good. It seems that Zhou Yu really cannot escape from Shenxiang.

"I want to run too." Fazheng said immediately.

Zhuge Liang glanced at the two of them, raised his hand to signal them to stop saying anything and leave quickly. Fazheng hurriedly said a few words of thanks, and then ran away decisively. Unlike Chen Xi, Fazheng still wanted to do more. Face, Chen Xi could run away at any time. It doesn't matter whether Zhuge Liang agrees or not. Do you think that is a question? No, that's a notification.

"Escape!" Chen Xi saw that Fazheng was also planning to leave early, so he waited for Fazheng twice, and the two of them left together, leaving Guo Jia alone on the other side. However, Chen Xi and Fazheng had no bottom line. Not seeing Guo Jia, he slipped away.

"Fengxiao, why don't you go and listen to the music too." Li You greeted Guo Jia who was gritting his teeth. Guo Jia packed up his things and ran away without saying a word. The Political Yuan quickly became cold, leaving behind Those who come down are all capable ministers in the true sense.

"You two bastards didn't even call me!" Guo Jia chased out and cursed at Chen Xi and Fazheng.

"We both have something to do when we go back. What are you going to do?" Chen Xi said angrily.

"I'll go back and teach my stupid son!" Guo Jia said with a bit of ridicule. Of course, this was not a lie. Guo Jia's son Guo Yi was indeed not very smart, and he did not inherit Guo Jia's unfettered wisdom. But Guo Jia didn't feel uncomfortable about this.

"Teaching? I think it would be better if you sent Boyi to General Zhang to practice martial arts. I feel that his body bones are a bit weak from you." Fazheng frowned and suggested.

Earlier, Fazheng didn't feel that Guo Yi was weak. After all, Fazheng was good at it. There was no comparison, so there was no harm.

But not long ago, Guo Yi was standing with a group of guys who were smaller than him, such as Liu Chan, Sun Shao, and Deng Ai. Fazheng realized that Guo Yi seemed to be really weak. How come those guys were so strong!

Can you not be strong? This group of people eat well, and some people urge them to train. It's strange that they don't get strong.

"I want to practice hard. During the time when Yunchang came back to practice, I took my son to see him. Alas, Yunchang's youngest son and grandson have started practicing martial arts." Guo Jia said with a sigh filled with emotion. He said in a tone of voice, "Time flies really fast."

"Tanzhi is really a good person." Fazheng added after hearing this.

One thing to say is that Fazheng and Guan Ping are not very familiar with each other. Fa Zheng’s circle of military commanders mainly consists of Guan Yu and Zhang Fei. What should I say to Guan Ping? Guan Yu asked Guan Ping to call Fazheng his uncle. Fazheng felt that this could not be done, but everyone It doesn't seem possible to talk about each other, because we are really close to each other.

Therefore, Fazheng was embarrassed to meet Guan Ping. Guan Ping also noticed this, and to be honest, the age difference between the two parties was actually not much different, so they usually met less often to avoid embarrassment. But what good could Guan Ping do? When picking up things, he would also remember to give Fa Zheng some time. For example, this time, Guan Ping also gave Fa Zheng a fruit horse for his newborn son who was not yet a hundred days old.

Guo Xima is the thing that Chen Xi's son Chen Yu broke out from Zhang Bao. At that time, Chen Xi thought it was a foal, but in fact it was not a foal, but a serious adult Guo Xima. This thing had an innate body shape. It is small, usually less than 70 centimeters tall, so it is indeed very suitable as a mount for children of Zhang Bao and Chen Yu's age.

When Guan Ping came back last time, he saw Chen Yu and Zhang Bao grabbing these things. When he came back this time, he brought a lot of them from the southwest, basically giving one to each child of this age group.

After all, everyone looks up without looking down, so as a junior, it doesn't matter if you give them a small gift. As for how these horses came, in Guan Ping's words, they were caught from the wild.

Although it sounds outrageous, there are really many wild animals these days. Even in the theoretical Han Dynasty, there are actually many places that are completely undeveloped.

"Indeed, Yu'er likes it very much, and Chen'er also likes it very much. The two of them rode horses together to chase the goose..." Chen Xi raised his head and thought for a moment before saying.

This is what Chen Xi saw with his own eyes last time. His eldest son taught his youngest son to ride on a horse and use a rope to trap a goose in the Bahe River. After roping the goose, he rode the horse and dragged the goose away. Although the horse was big He was too young and could not run fast, but after riding on the horse, Cai Chen, who instantly gained three laps of courage, really lassoed a big goose under the leadership of his eldest brother and his eldest brother, Chen Tai.

When Chen Xi saw Cai Chen at that time, he saw that the other party was holding on to the noose, blushing and not letting go. He was very excited and lively, and his speech was no longer as gentle and soft as Cai Yan taught him. It was a fierce roar, and it was obvious that he was very excited.

Of course, to Chen Xi, this child probably has the spirit of a boy. If Cai Yan continues to raise her like this, she will become a daughter.

"I feel like boys should be more wild when they are young. After having this horse, Chen'er has become a lot more naughty. It is completely different from the well-behaved person before. It's good." Chen Xi said with a smile.

"Speaking of which, did you really let this child's surname be Cai?" Fazheng said with a frown. These days, people are still very particular about this. It would be fine if Chen Xi didn't mention Cai Chen. After mentioning it, Fazheng would inevitably ask a few questions.

"Don't you know that the old Chen family has a tradition?" Chen Xi was silent for a while, feeling that there was no way to argue with Fazheng on this matter using normal logic. After all, even Liu Bei, a guy who strongly supports him, is here. Chen Xi couldn't understand everything, so Chen Xi felt that he needed to describe this matter with some facts that seemed illogical, but happened all the time and were recognized by people.

"What tradition?" Guo Jia squinted at Chen Xi, as if to say, I'm a native of Yingchuan here, come on, make it up, I want to see what you can make up.

"What should I say?" Chen Xi strode forward with his hands behind his back. After walking a few steps, he looked back at Guo Jia and Fazheng who were standing there. "Chen's has a characteristic, that is, Chen's direct veins can stabilize The birth of an elite figure of the same generation, but no matter how outstanding this elite figure is, when the branch line rises, the light of this elite figure will be overshadowed by the genius of the branch line. "

Guo Jia was silent for a while after hearing this. As a native of Yingchuan, he knew this joke, especially after working with Chen Xi for many years. Guo Jia had a clear understanding of this thing. This thing that sounds outrageous, if you really want to say it , is actually realistic.

Sima Ranju, Sun Wu, Sun Bin, Kuang Zhang, not to mention civil servants, each of these people were scornful of the elites of the Chen family in their contemporaries.

"So releasing Cai Chen is not necessarily a bad thing, right." Chen Xi said with a smile, "Maybe it is not a good thing for the Chen family, but it is definitely not a bad thing for me. Besides, it can also please Zhao Ji. Make it easier for me, right?"

"Thank you for your good attitude." Fazheng curled his lips and said. The surname passed down from the ancestors, and the number assigned to the Y chromosome is the essence of the surname. Without changing the surname at will, the same surname represents the same Y chromosome, although Fazheng does not have this awareness, Fazheng will not accept changing his cub's surname at all.

"I don't pay much attention to this kind of thing." Chen Xi waved his hand and said, "I really have something to do and need to leave first. You can contact me later if you have something to do."

"What's going on recently?" Fazheng raised an eyebrow and said, "Come to my house for a drink tonight if you have nothing to do. Forget about the invitation. It's rare that most people are here in Chang'an recently."

"What's going on in Jiangdong? Pang Shiyuan has judged that Meng Kangbu is about to arrive. I have to release Gong Jin quickly. To be honest, even if Xingba is driving a seventh-generation ship, I am somewhat worried." Chen Xi sighed and said, "Meng Kangbu is about to arrive." Combo's strength is quite good. If the seventh-generation ship fights head-on, I'm not worried that Xingba will lose to Mengkangbu. The problem is that if Mengkangbu sees the appearance of the seventh-generation ship, it will be really hard for him to fight head-on. There’s just something wrong with my brain.”

"Speaking of which, has the submarine problem been solved?" Guo Jiayi asked with a raised eyebrow.

If Mengkangbu were to dive all the way, it would be difficult for the Han Dynasty to deal with both observation and attack. After all, the secret technique of water flow buffering developed by Kushan was really disgusting. The sea water itself would absorb the impact, and further After enhancing this effect, Moncomb's fleet was hiding under the sea at a depth of three to four hundred meters. Unless the seventh-generation ship's gun can directly hit it, it is difficult to cause damage.

"There is no need to solve it. The Strait of Malacca becomes shallower towards the southeast, and the general water depth is 25 meters." Chen Xi shook his head and said, "Degui's navy is there."

I get up early to work. I feel like I'm really useless. Please vote as many as you can. There's something really wrong with the author's level of struggle. Sigh.
