Mingjia, a scientist in Qing Dynasty, created Catalan numbers.

Mingjiatu was a famous scientist in Qing Dynasty. He made great success in the study of arithmetic pi and successfully drew the topographic map of ancient China. So how did Mingotto introduce this role in the introduction?

In the introduction of Minggatu, Minggatu was introduced as a Mongolian in Qing Dynasty. He was born in Kangxi Shengshi 1692. He also successfully became an official in 17 10. His talent was outstanding, and he was appreciated and valued by Emperor Kangxi. Later, after Yong Zhengdi and Gan Long, they never relegated. It can be said that their official career is relatively smooth. Ming Jiatu studied the topography of other places all the year round, and finally successfully drew a map of China in Qing Dynasty, which can be said to be an outstanding contribution.

Mingjiatu was born in the heyday of Kangxi, and the Qing Dynasty was peaceful. Mingjiatu has the opportunity to devote himself to scientific research. In his early years, Ming Gatou served as a satrap, mainly responsible for studying the sun, moon and stars and fortune telling. At the same time, Mingatu actively learned advanced scientific knowledge from western missionaries, broadened his horizons and learned more about human beings and astronomy. Later, Ming Artu began to compile astronomical books and arithmetic books, and made great achievements. Mingatou is proficient in geographic informatics. He made many field trips to all parts of the motherland and began to draw maps. In the long-term research, Mingatou gradually discovered the "tangent circle method", and made a systematic summary of it, and wrote a famous arithmetic article.

Mingjiatu was a very great scientist in Qing Dynasty. His achievements in astronomy and mathematics are unparalleled, so there is a starry sky called "Ming Ge Tuxing". Minggatou died on 1765 at the age of 73.

The number of Catalans found in Mingatou

Minggatou was an outstanding scientist in Qing Dynasty. He has made great contributions in the field of mathematics. He not only creatively put forward the "tangent circle method", but also discovered the Catalan number. The name of Catalan number was put forward by the western mathematician Catalan. In fact, Mingato was the earliest founder of Catalonia number. Ming Artu began to study western advanced mathematics in his early years. After constant thinking and exploration, he finally found the Catalan number in the knowledge related to trigonometric functions. However, Mingato did not systematically study this discovery at that time, but it also opened the way for people to learn Catalan characters.

Taran number was first discovered by Ming Atu, a mathematician in Qing Dynasty in China. Ming Artu's related work "Secant Circle Density Rate Method" is also recorded. However, the study of Mingatou is not very in-depth, but only stays on the surface of Catalonia number, focusing on the geometric significance of Catalonia number. In the process of studying combinatorial arithmetic, Mingatou gradually found that too many numbers were difficult to express by counting, and creatively invented Catalan numbers characterized by trigonometric functions. Mingatou found that finite sequences and finite functions still exist in Catalan numbers. He did a lot of research on them, but in the end he didn't get very convincing axioms and inferences, so no one cared about them.

Catalonia numbers were first discovered by lorla, but they were not named after him, which made many people feel sorry. So someone suggested renaming the Catalonia number. At present, this naming method has not been formally adopted, but it also marks that Mingato is recognized by the world as the first person to discover Catalonia numbers, which is also the best recognition of Mingato's great achievement in discovering Catalonia numbers.

Mingato's achievements

A famous scientist in Ming Dynasty. He has made great achievements in many fields, especially in mathematics and geography. Mingjiatu was born in Kangxi and died in Gan Long. After three dynasties, he has been studying astronomy and geography seriously. In fact, Mingatou has made great achievements not only in geo-informatics, but also in literature, among which his book Calendar of Destiny is the most famous.

There are two main reasons why Minghetu has made such great achievements. One is that Mingjiatu was born in the heyday of Kangxi in the Qing Dynasty. At this time, the peace and stability of the country also gave him the opportunity to give full play to his talents. The second reason is that Mingjiatou studied hard by himself and finally achieved amazing results. Ming Artu's achievements in mathematics are the most remarkable. He creatively invented the "tangent circle method", which was rare at that time, when he was studying the pi in China's ancient arithmetic. In addition, Ming Artu also invented several equations, which provided a shortcut and convenience for solving the triangle problem. At the same time, Ming Artu also traveled to famous mountains and rivers, carefully studied China's geomantic omen, and successfully used modern methods to draw maps. Fundamentally speaking, it laid the foundation of modern China map mode and successfully solved many practical problems of inconvenient travel.

Ming Artu's great achievements are mainly attributed to his efforts. When he was studying, his intelligence was outstanding and his thinking was profound and agile. During his career, Mingato was able to devote himself to his work. While doing his job well, he focused on mathematics and astronomy and finally achieved excellent results.
