2) Let f(x)=2sin(x)x (a) Plot the function f(x) for x[1,3]. (b) Write an R function that implements the bisection method. Your function needs to keep track of the sequence of vulues x 's ss the method converges to a root. (c) Repeat (b) for Newton's method. (d) Find the root x4 of f(x) via bisection using e=11014 (c) Find the root x of f(x) via Newton's using =11014. (f) Look at x4x for all values of is For both the bisection and the Newton methods. What does this tell you about the convergence rate?.
