For f(0) = sin cos 0 + cos 0 for 0 02 Find where f(0) is increasing and decreasing, and where it has local max and min values. Hint # 1: Once you've taken the derivative and set it equal to zero, convert all trig functions to the same trig function using the identity cos(0) + sin(0) = 1. Hint #2: Then make a substitution 1 = sin(0) or u = cos(e) to make your equation look like a quadratic equation in u. Solve for u, then find 0.
