f(x) = cos² (3x + 6) maka  f '(x) = -6cos(3x+6)sin(3x+6)
a. f(x) = -6 sin(6x + 12) maka f'(x) = -36cos(6x+12)
b. f(x) = -3 sin(6x + 12) maka f'(x) = -18cos(6x+12)
c. f(x) =  -sin(6x +12) maka f'(x) = -6cos96x+12)
d. f(x) = -3 cos(6x +12) maka f'(x) = 18sin(6x+12)
e. f(x) = -6 cos(6x + 12) maka f'(x) = 36 Sin(6x+12)
