Halley's Method

Halley's Method (the method of tangent hyperbolas) for finding roots including history, derivation, examples, and fractals. Also discusses Taylor's Theorem relating to Halley's Method as well as Halley's Comet. Sample code and images available on GitHub https://www.github.com/osveliz/numeri...

Corrections: The example at 8:08 had an error with the programming of f'(x). The bug caused the numbers in the table and the plots for that example to be incorrect. There is a separate issue in that example where 2 was written as the input instead of -2. Also there is typo in the name Christopher Wren at 0:46. A video covering these corrections can be found here    • Video Mistakes and How to Fix Them
