The methods are Newton's method and Halley's method, defined, respectively, by f (zk) NEWTON: Z(za) Your tasks are enumerated below. Use Rouch's theorem to find the best upper bound you can on the moduli of the zeros of the polynomials pi and p2. Compare to the exact values. Write Matlab functions that evaluate pi, p, and p at a point z. Call these functions pl.m, dpl.m, and ddpl.m, respectively. They have one input and one output. Create another three Matlab functions by doing the same for p2. Give them analogous names as for pi The methods are Newton's method and Halley's method, defined, respectively, by f (zk) NEWTON: Z(za) Your tasks are enumerated below.
