User blog:Dalek-James/Happy Pi day!

Hiya folks.

Today is national pi day so I thought I would tell you a little bit about how to calculate pi.

Pick any random number to be n. Then use the equation n(sin(180/n) to give you a rough approximation of pi. The higher the value of n, the closer you get to pi. n=5 doesn't even get you to 3 but n=100,000 gets you to 3.141592653...
