7. (40points) Computer project We want to nd an approximate root of the following nonlinear equation + cos z sinx - 3= 0 (1) (10points) Determine an initial interval [ao, bo] containing a root a off, in order to apply the bisection method. Use lan bnl 0 to implement the bisection method with some speci ed tolerances (stopping criterion)e = 10-6 for the convergence. How many steps of the bisection method are needed to obtain an approximation? Does it satisfy the formula derived from the previous problem #3(2). (2) (10points) Implement the Newton's method with initial points Xo = -2, 1, 10.
