1. Using 21 equally spaced nodes on the interval [-5, 51, find the interpolating polynomial p of degree 20 for the function f (x) xe 1) Print the values of f (x) and (x) at 41 equally spaced points, including the nodes observe the large discrepancy between f(x) and p(x). 2. (Continuation) Perform the experiment in the pre- ceding computer problem, using Chebyshev nodes xi 5 cos (int /20), where 0 S i S 20, and nodes xi 2 Where 03 i 3 20. Record your con- clusions
