Estimating π using polygons

Using Julia to play around with shapes and pies

I thought a lot about what to post on π day (March 14th). I’ve already written an article about estimating π with Monte-carlo methods here, so I couldn’t do that again. Then I remembered that back in high school we were shown a different way of estimating π: by using n-sided regular polygons. So I got my Pluto notebooks out and grabbed Plots.jl to cook something up for this article.
