Question:
Use the method of Example 6.83 to evaluate the given integral.
∫ ( e2x cos x - 2e2x sin x)dx. (See Exercise 15.)
Data From Exercise 15
Consider the subspace W of D, given by W = span (e2x, e2x cos x, e2x sin x).
(a) Find the matrix of D with respect to B = {e2x, e2x cos x, e2x sin x}.
(b) Compute the derivative of f (x) = 3e2x - e2x cos x + 2e2x sin x indirectly, using Theorem 6.26, and verify that it agrees with f′(x) as computed directly.
