The Reguli Falsi is a root-bracketing method, which can run into trouble when one one end of the root-bracketing interval converges to the root. I found an interesting article on the Internet an article titled "A family of regula falsi root-finding methods" by Sérgio Galdino. This article shows several remedies for the Reguli-Falsi's problem. Each remedies allows the root-bracketing interval to properly shrink around the root.
