In this lesson, we learn all about pi, including what it is, how to calculate it, where it is found, and fun facts and activities that can be done with pi. We discover that pi is an irrational and transcendental number that represents the ratio of the circumference of any circle to its diameter. There are several algorithms for computing pi, and some people can even memorize it to tens of thousands of digits. However, it is useless to calculate pi to so many digits, as even circles of great magnitude do not require such precision.
A video discussing pi. This video talks about what pi is, how to calculate pi, where pi is found, and fun facts / activities with pi.
This is great for a person who wants to learn more about pi, especially on or around Pi Day. Ideas are presented clearly and thoroughly with a brief introduction to several aspects of pi. The resources also do a great job providing more information on pi.
