Qin's achievements in mathematics are basically reflected in his "Nine Chapters Calculation Book". However, this book did not cause much influence at that time. Later, neither Yang Hui nor Zhu Shijie quoted Qin's achievements. The main content of Shu Shu Jiu Zhang focuses on the application of mathematics, and 8 1 topics in the book are all questions put forward in combination with the actual needs at that time.
Qin also pioneered the "three-oblique quadrature method" and gave a formula for calculating the area of three sides of a known triangle, which was completely consistent with Helen's formula.
Qin was a famous mathematician in the Southern Song Dynasty. He paid equal attention to theory and practice, was good at inheritance and innovation, cared about the national economy and people's livelihood, observed the sufferings of the people, advocated benevolent government, and supported and participated in the war against gold and Mongolia.
His method of seeking greatness and broadening, positive and negative cholesky decomposition and his masterpiece "Several Books and Nine Chapters" are a dazzling page in the history of Chinese mathematics and even the history of the world mathematics, which has had a wide impact on the development of mathematics in later generations.
Qin Memorial Hall is located in the cave, covering an area of 8 1 m and a building area of 1.538 m2. This is an ancient building imitating the Song Dynasty, with several books and nine chapters, Jiu Shao's hometown, observatory and other scenic spots.
In June 2020, Qin was selected as "the second batch of historical celebrities in Sichuan Province" by the leading group of Sichuan Historical Celebrity Cultural Inheritance and Innovation Project.
