Regula falsi - Wikipedia
https://en.wikipedia.org/wiki/Regula_falsiWhen solving one equation, or just a few, using a computer, the bisection method is an adequate choice. Although bisection isn't as fast as the other methods—when they're at their best and don't have a problem—bisection nevertheless is guaranteed to converge at a useful rate, roughly halving the error with each iteration – gaining roughly a decimal place of accuracy with every 3 iterations. For manual calculation, by calculator, one tends to want to use faster methods, and they usually…
Online calculator: False position method
https://planetcalc.com/3712False position method. False position method or 'regula falsi' method is a root-finding algorithm that combines features from the bisection method and the Secant method.. As in the secant method, we use the root of a secant line (the value of x such that y=0) to compute the next root approximation for function f.
