Liu Jianhui was the greatest mathematician in Wei and Jin Dynasties. He made great contributions to the establishment and development of China's classical mathematical theory, and occupied an important position in China and even in the history of mathematics at that time. Next, let's take a look at the profile of Liu Hui.

Liu Hui was born around 225 AD and died in 295. At that time, he was the most outstanding mathematician in the world. His works in this field have a vital influence on the development of mathematics in later generations, and also laid his unshakable position in the field of mathematics, leaving the most precious cultural heritage for the field of mathematics.

Liu Hui is quick-thinking, diligent and studious, and has made remarkable achievements in mathematics, which can be roughly divided into two aspects. One is that he studied China's ancient mathematical theory, thus sorting out a set of mathematical system, which can be seen from his mathematical works. His relatively complete set of mathematical theories includes general points, reduction points and various arithmetic rules, and proves theoretically the existence of the square root of irrational numbers. Liu Hui also gave a clear definition of the rate, and then passed it? Rate? To define? Equation? ; At the same time, he also developed Pythagoras theory.

The second is the area and volume theory. He put forward the principle of Liu Hui, which solved various problems of area or volume. In addition, in his own works, he also gives the calculation method of Youzhou rate, which makes pi become? Benefit rate? .

Liu Hui has been roaming in the ocean of mathematics, constantly studying and learning, putting forward new ideas and theories, and making great contributions to the development of mathematics.

Liu Hui and Liu Pi Hui are famous mathematicians in ancient China. He invented it? Circumcision? , laid the foundation for the calculation of pi, and his works were regarded as the treasures of mathematics. So, what's the story between him and Pi? Liu Hui was the greatest mathematician in Wei and Jin Dynasties, and his theory had a far-reaching impact on the development of mathematics in later generations. It was Liu Hui who put forward the calculation method of pi, which made China always in the leading position in the calculation of pi.

So what is pi? Why do you need pi? What is the so-called pi? The ratio of the circumference to the diameter of a circle. Pi is directly related to the calculation accuracy of spheres and circles. Liu Hui used it? Circumcision? Cut a circle from a circle inscribed with a regular hexagon. So he found that as long as he cut more carefully, the gap between them would become smaller and smaller. What he said was to the effect that? The thinner you cut, the smaller the gap. Cut and cut until you can't cut any more, and it can completely coincide with the circumference without gaps. ? In order to prove this theory and calculate pi more accurately, Liu Hui worked very hard, and finally calculated the area of 3072 polygons, and verified that pi was 3. 14 16.

Hui has been persistently calculating the approximate value of pi. Did he propose it? Circumcision? It also provides a theoretical basis and a perfect method for the calculation of pi, and then pi is 3. 14 16. This was a big step ahead of others in the calculation of pi in the field of mathematics at that time, which made China have a high starting point in the calculation of pi.

Liu Hui's masterpiece Liu Hui is a very great mathematician in the history of China. His representative works "Nine Arithmetic Notes" and "Calculation Classics on the Island" are the treasures of Chinese mathematics, which are of great significance to the development of mathematics. Next, let's meet Liu Hui's representative works.

Liu Huisheng was born about 250 years ago. He devoted himself to mathematics all his life, worked tirelessly in the ocean of mathematics and put forward many important theories. He summed up his own research and wrote Nine Chapters Arithmetic Notes, Calculation Classics of Islands and Nine Chapters gravity difference Map. Unfortunately, after many years, Liu Hui's last two works have lost their trace in the Song Dynasty and are nowhere to be found. However, Liu's important position in mathematics is unshakable.

Nine Chapters of Arithmetic was written in the early Eastern Han Dynasty, in which 246 problems were solved. But these solutions are relatively primitive, and Liu Hui made some supplementary explanations. In these explanations, we can clearly see the depth of Liu Hui's specialized research in mathematics. He first put forward decimals, and connected the cubic roots of irrational numbers with decimals. In addition, he also explained positive and negative numbers, which made a great contribution to geometry.

However, the island calculation book is the earliest survey work in China. Nine questions in the book calculate the height, depth and width through measurement. Because the first question is about the calculation of islands, this topic is given.

Liu Hui's two works contain profound scientific thoughts. Liu Hui used all kinds of excellent ideas to make innovations in mathematical research on the basis of inheritance, and also made mathematical research enter a brand-new stage.
