WE HAVE TO USE MATLAB:
Use the bisection method to find the root of the equation f(x) = x2 - 4sin(x) = 0.
For initial bracketing interval [a,b] , take a=1 and b = 3.
Please note that the values for "a" and "b" are changing at every iteration and accordingly new values for f(a) and f(b) would be computed as well.
