What research did Kangxi do about mathematics? What level of mathematics did Kangxi reach

Kangxi's level of mathematics has reached the level of accurately judging the academic achievements of that time.

Mei Wending, a great mathematician in the early Qing Dynasty, wrote the book "Calendar Questions" and submitted it to the palace. After some careful study, Kangxi came to the conclusion that "the book presented was very careful, and the discussion was fair, and this person worked hard", he thought that the writing was very careful, and the views were also fair.

Emperor Kangxi's level of mathematics should be the best among the emperors of all dynasties"Meta""times""Root (solution)."These modern mathematical terms were also originally formulated by Kangxi in China.

One of the emperor's teachers when the Kangxi Emperor was fourteen years old was the Belgian missionary Nan Huairen, who taught the emperor astronomy and calendrical calculations. Emperor Kangxi also studied the first few chapters of Euclid's Geometry Originals translated by Matteo Ricci and Xu Guangqi, and ordered them to be translated into Manchu and Chinese. The emperor played a good abacus, and the speed was faster than the Western Pha.

Related Notes:

Kangxi presided over the compilation of "The Essence of Mathematics and Physics", which is known as an encyclopedia of mathematics. He first proposed the terms of equations such as "yuan", "order", "root" and "solution" that we encountered in mathematical problems. In solving the right triangle problem, the solution of "finding the Pythagorean by the product" was invented and created by Kangxi.

Kangxi vigorously developed his own mathematical talents, and also hired missionaries from the West who were accomplished in mathematics, astronomical calendar, etc., to give lectures in China, which greatly improved the level of Chinese mathematics. He also corresponded with Leibniz, Germany's greatest mathematician, and established an institution similar to the Academy of Sciences.

That's because Kangxi is interested in mathematics, and has gained a certain sense of accomplishment in mathematics, and Kangxi is very satisfied, so Kangxi will always learn Qiuxia.

Because he felt that mathematics would be of great help to him in managing the world, for example, he could use mathematics to count the number of people in each province and city, as well as the grain and grass in the treasury, and Kangxi also used mathematics to make the envoys of other countries who wanted to humiliate him suffer a big loss, so he has always been particularly diligent in studying mathematics.

Because he felt that mathematics was important. So he had to study mathematics hard and become the best emperor in history.

(1) m=96 6=16, m=root number s, that is, root number 16=4, then the three sides are 12 16 20

2) Can, S 6 = m, the root number m = k The three sides are 3 roots S 6, 4 roots S 6, 5 roots S 6, (3 roots S 6 + 4 roots S 6) square = 5 roots S 6 squared, that is, the square of the right triangle A plus b is equal to the square of C.

(1) Just use the formula, 2) Get 3 points, it should not be difficult to prove. Proven by the title, it is a matter of calculation, attention to detail.
