(c) Use tzero to find when the derivative of 5 f(x) = cos(x) + 9 sin(x) in in the interval (0, x/2). (d) The function S(x) = x - x - x - x - * - 1 has a real zero near 2. Find it: (e) The same function has a critical poleyn (-2, 1). Make graph to find a good approximation, then use tzero mathod to find a more exact value for the critical point, The approximate critical point is:
