We start by finding the first derivative. f'(x) = cosx - sinx Since this is defined on all real values of x, there will be no vertical tangents. However, there will be horizontal tangents, when f'(x) =0. These will be our critical points. 0 = cosx- sinx sinx =cosx The only time this happens in the given interval is at x = pi/4 and x= (5pi)/4. At x = pi/2, we see that the derivative equals f ...0 votes. (a) Find the intervals on which f is increasing or decreasing. (b) Find the local maximum and minimum values of f.
