The code starts by importing the necessary libraries and taking user input for the initial values, desired relative error, and number of iterations. Then, it initializes arrays to store intermediate ...

''' root = bisection(f,x1,x2,switch=0,tol=1.0e-9). Finds a root of f(x) = 0 by bisection. The root must be bracketed in (x1,x2). Setting switch = 1 returns root = None if f(x) increases upon bisection ...
