Liu Bin was very drunk. Seeing that the one who refuted Wu Zong was his new son-in-law, he couldn't help but be very interested. He held the wine cup in his right hand and said, "Jinzhou, tell me what is the critical wind?"

"It's calculus, advanced geometry." Cheng Jinzhou raised his sleepy eyes, looked at the eyes around him who were "full of knowledge" and said: "It's as simple as land measurement. There is no piece of land, it's really neat and uneven. How to deal with it is what calculus needs to do."

Wu Zong also drank too much wine and shook his hand and said, "If there are uneven places, you need to use the techniques of cutting and replenishing the body. The mystery of cutting and replenishing the point is something that can't be said in the past ten years."

"Can't it be mysterious? You're using finite to calculate infinite." Cheng Jinzhou seemed to be back in college in a trance, and he seemed to be teaching undergraduates instead of an unscrupulous doctoral supervisor. His face was full of smirking of abducting female students: "The real irregular figures, no matter how you cut them, will eventually be estimated. As long as you estimate, there will be a difference, so how dare you guarantee it? Real mathematics can only be accurate, not accurate."

Wu Zong shuddered and woke up halfway through the wine. He said in disbelief: "Can you calculate the irregular figures directly without cutting the supplement?"

Liu Bin asked in a slight silence: "What does Mr. Wu mean?"

Wu Zong did not answer, but just looked at Cheng Jinzhou with a steady attitude. Mathematics is a very realistic thing, and there is no point in being illusory. Since the latter can understand some of the cutting-edge problems like the Seventeen-sided shape, it is naturally not a targetless person.

What's more, he was recognized by Liu Kuang's fourth-level star sorcerer.

With the physical fitness of the sick-growing bird, Cheng could get drunk with a few glasses of wine, but he vomited for a while and was a little more sober, which made Cheng Jinzhou slapped his tongue and said: "It's a fractal geometry that has nothing to do with me, but if I were to test the land or something, I could still use the calculus at will."

He said, dipping his hands in wine and drawing twisted on the tablecloth.

The astrology wise men worshipped by the Cheng family were somewhat interested, and several nobles with higher status were squeezed together.

Cheng Jinzhou casually drew the simplest waveform curve, which is the first graphic in any calculus textbook, and muttered: "Just treat a curve as a collection of many points, can that figure be accurately measured? The finer your point is, the higher the accuracy, until you are exhausted."

No idea appeared suddenly. The core concept of calculus is "limit", which was perfected by Cauchy in the 19th century, and the limit can be traced back to the "poor method" of Greece in the 5th century BC. Wu Zong absolutely could not understand the formula used by Cheng Jinzhou, but he could quickly understand the other party's ideas.

Some rice wine had already evaporated and didn't know where to go. Wu Zong also reached out to dip it in the wine. He didn't care about the soup that was rubbed on his sleeve, and drew two simple irregular figures and said, "If you put your method in it, we will calculate the result..."

"Can calculus prove it with attempts or lists?" Cheng Jinzhou looked down on Wu Zong with his wine eyes. Despite this, he still gave the answer.

Of course, it is undoubtedly correct.

"I'm not clear about my mind, my fault." Wu Zong's lips became dry and he didn't even care about curling his beard. After admitting his mistake, he immediately said, "How did this formula come up?"

"This is called deduction, and it is not a formula." Cheng Jinzhou wiped his hands with a tablecloth and said, "The process is very cumbersome and I'm too lazy to write."

There is indeed a lot of content, but the main thing is that Cheng Jinzhou cannot remember it all.

Wu Zong was embarrassed to speak, and Liu Bin next to him smoothed out: "Mr. Wu, what kind of mystery are you fighting? You have to tell us."

At this time, it was Wu Zong's turn to be impatient. He just looked at the identity of the other party's earl and said with a stern expression: "Whether it is a river beach or a forest, it is not a regular shape. This technique of cutting and repair is to see that it has an extra piece and cut it down and fill it up in a place where one piece is missing. There will always be some mistakes in this way. No matter how good astrology warlock is, it will never be able to cut and repair balance. It is enough to use it in normal times, but if Mr. Cheng's method is correct, it can not only be used in the measurement of the land."

The group of people were amazed. It was really not enough to say the status of calculus in mathematics, but for these nobles, a little bit of real and simple meaning is more likely to be appreciated.

Cheng Jinhao looked back with lingering fear. The ladies and ladies had long been smothered by the deep processing smell, but they did not see Cheng Jinzhou's performance at all.

Thinking of Liu Qingshuang only seeing Cheng Jinzhou's ugly appearance, Cheng Jinhao felt a little spiritually happy - even if he was gossiping everywhere, the taste was completely different from seeing it on the spot.

The astral warlocks looked at Cheng Jinzhou at this time, their eyes so eager that they seemed to be as if the fat man who was losing weight saw the flesh, his eyes were covered with 3 mature bloodshots, and he was almost waving his knife and fork.

Cheng Jinzhou vomited for a long time, and with the passion of waving his wine hands, his mind was awake. Seeing the standard calculus figures on the tablecloth, the remaining alcohol was evaporated by cold sweat. At this time, he was not willing to talk to them. He ignored the dish basin on the table and grabbed the tablecloth and tore it, and rolled it up and was about to leave.

Everyone looked at him and inadvertently made a move automatically - a capable astral warlock is always the most popular person on this planet.

Only Liu Bin smiled and touched his beard, admiring himself. When Cheng Jinzhou was about to walk out of the door, he waved his hand and shouted: "Son-in-law, remember to come and chat with the old man tomorrow."

The figure turned the corner, and he was still waving there.

The banquet ended naturally, the process was very dramatic, and the result was very beautiful. It was a joyful thing for the host and guests, and even a little too much. Liu Bin returned to his residence, still touching his beard and smiling.

Mrs. Liu, who came back first, was a little unhappy. While directing the girl to wash the master's face and change clothes, she said half-resentful: "How can you promise a marriage like that? Don't discuss it at home? I saw Cheng Jinzhou. I heard that it used to be a medicine jar, but now it's better. It's too late to go to school..."

The ladies of the Great Xia Dynasty still had a certain status, which was somewhat like France during the Louis XIV. Mrs. Liu kept talking about the bad things about Cheng Jinzhou.

Liu Bin just smiled and waited for the hot towel to apply on his face to remove it, then he let out a sigh of relief, turned his head and asked, "Shuang'er, what do you think?"

Liu Qingshuang shook her head gently and said, "Shuang'er just doesn't understand why her father values ​​him."

She fought back with a well-behaved and roundabout way.

"I responded well to this sentence and deserved that boy." Liu Bin commented first, then smiled happily and said, "That boy is not simple, but his body is indeed weaker. Well..., let's give him Meng Da and Meng Er."

Mrs. Liu paused her hand and said in surprise: "They have saved your life in Tucheng. You also praised them for being brave..."

"It is only a warrior like this that deserves a great astrology warrior." Liu Bin raised his head slightly and said, "I always look at people very accurately."
