Online course “Liu Hui and the Circle Dissection Algorithm”

 

The objective of this course is to introduce the mathematical achievement of the ancient Chinese mathematician Liu Hui (A.D. 220 to A.D. 280) in finding the approximate value of π. Firstly, the course briefly explains how to estimate the value of π by considering the area of an inscribed regular hexagon of a circle. It follows how Liu Hui used the Circle Dissection Algorithm to reach the value of π as 3.14, correct to the nearest hundredths, which is the well-known “Huilu”.
