Secant Method - Mathematical Python
https://www.math.ubc.ca/~pwalls/math-python/roots-optimization/secant
Secant Method. The secant method is very similar to the bisection method except instead of dividing each interval by choosing the midpoint the secant method divides each interval by the secant line connecting the endpoints. The secant method always converges to a root of f ( x) = 0 provided that f ( x) is continuous on [ a, b] and f ( a) f ( b ...
