Question 1. Apply two steps of the Newton's method to the equation x3 = 2x + 2 with initial guess x0 = 1. Show the iterations x1 and x2.

Question 2. Consider the function g(x) = x sin x. Find an interval where for each x0, the fixed point iteration xk = g(xk-1) always converges to the fixed point x = 0. In the case of convergence, what is the rate of convergence?

Question 3. Consider the matrix,
