Hi,
How can I write a single script which tries to find the roots of the following functions using both the Bisection and Newton Raphson methods? Also I want to generate a plot of the functions showing the location of the initial guess(es) and the approximated root value..
Function Interval Tolerance
f(x) = 2sin(x) + 2cos(x) [-1 1] 1x10-3
f(x) = 2-sin(x) – x2 [-1 2] 1x10-4

This is a very common numerical methods assignment. Have you tried searching the forum yet? Chances are this question has already been answered many times.

This line is incomplete:
while abs(myFunction(x_mid) >
How do I find the lower and upper limits? - You have to guess them. There is no way to find then in advance.
