Question

Use the Newton's Method to approximate the real root of the equation:

f(x)=x-2+cosx=0

a) What is the iterative equation of Newton's method of the given equation?

b) Iterate the equation with starting point x1=5 until you get a repetition of the four digits after the decimal point.
well, f'(x) = 1-sinx

So plug that into Newton's method. Here is a nice web site:
