A mathematical formula named after a mathematician in China.
Mathematics has a long history of at least 5,000 years in China. Mathematicians in China have added rich works to the kingdom of mathematics. Some theorems and formulas are regarded as rare treasures and will be left in the name, which really makes Chinese descendants proud and annoyed. Shang Gao (about 65,438 BC+the 2nd century BC) was a doctor of the Zhou Dynasty and was proficient in astronomy. He discovered a special case of Pythagorean theorem, which was once called "quotient height theorem". 2. Benefit rate *. Liu Hui (about 225- 295), who calculated the area of a polygon with 3072 sides in a circle through left and right calculation, got 223927/ 125. . 3. 14 16 was the highest record in the world at that time. In practical arithmetic, he advocates using 2 = 157/50 "3. 14, so the' value' of 3.14 or157/50 is called' emblem rate'. (Li Di's Outline of the History of Chinese Mathematics, 84th edition, P. 10. 1). 3. Ancestor rate. Zu Chongzhi (429-500) calculated that it would last for thousands of years. World record of value. Japanese mathematician Kazuo Mishima called Zu Chongzhi's "Secret Method" 355/ 1 13 "ancestral rate, (same as the second part, p. 1 15). 4. Zula principle. Zuchi (5th-/kloc-0th-6th century) was put forward by Zu Chongzhi's son. Grandfather.
