More on Root Finding: The Bisection method Using Python

In previous videos, we have used the Newton’s method to find the roots of various functions. In particular, we inverted the Black-Scholes model to solve for the implied volatility of an option. There are, however, other algorithms that can do this. Here, I present the bisection method. This is a quick video showing the basics of the technique. I don’t go into detail with the volatility as we have done that in several previous videos.
