In Exercises 1 and 2, follow the instructions for Exercises 1-4 using f(x) instead of x. 1.

Question:

In Exercises 1 and 2, follow the instructions for Exercises 1-4 using f(x) instead of x.
1. f(x) = 2 sin x - 3 cos x, B = {sin x + cos x, cos x}, C = {sin x + cos x, sin x - cos x} in span(sin x, cos x)
2. f(x) = sin x, B = {sin x + cos x, cos x}, C = {cos x - sin x, sin x + cos x} in span(sin x, cos x)
