Then the python program to perform the Secant method is as follows ?Open Compiler # Importing module from pylab import * # Defining Polynomial function def f(x): return x ** 2 + 3 * x - 10 # Defining function fo
% Matlab script to illustrate the secant method % to solve a nonlinear equation % this particular script finds the square root of a number M % (input by the user) % note that the function we are trying to zero is f(x) = x^2 – M. % this function is hard-coded in the script. ...
Algorithm secant(x1, x2) Input: Two initial guess for root. Output: The approximate root of a non-linear equation f(x). Begin f1 := f(x1) f2 := f(x2) x3 := ((f2*x1) – (f1*x2)) / (f2 – f1) while relative error of x3 and x2 are > precision, do x1 := x2 f1 ...
