Using Excel to Calculate π Like Newton

Happy belated Pi-Day.

In this video, I show how Newton calculated π (pi). I explain the reasoning, with a combination of algebra and a little calculus, and do the full calculation in Excel. If you've taken Algebra 2, you should be able to understand 95% of the video.

Thank you for the very nice explanation of Newton's derivation of Pi with matching excel calculation! And yes, a presentation from your perspective of Binomial Theorem would be appreciated. Thanks again.

The fact that Pi Day is not a National Holiday is irrational.
