find the value of c guaranteed by the mean value theorem for y=cosx on the interval [0,pi/2]

mean value thm says that f(x) is continuous on that closed interval, and differentiable on the open interval.
also, f(b)-f(a)/(b-a)=f ' (c)
i did the last hting out, and got f '(c) to equal -.6366, is this right? i dont know what im doing!
