Program 9-1:

-1 (a) Use the composite trapezoidal method code MATLAB Program 9-1 in the textbook, with h 0.2 (thus, N-10), to compute the above integral; also compare to the above exact result and compute the relative error; (b) Use 5 evenly spaced points (2 intervals) and the composite Simpson 1/3 rule (eqn. 9.19)) to compute this integral. Compare to the exact result and compute the relative error
