Since both cos(x) and cos(2x) are bounded by -1 and 1, the absolute value of 2cos(2x) will always be double the absolute value of cos(2x). Since the first derivative represents the rate of change of a function, the absolute value of the rate of change of y=sin(2x) will be double the rate of change of y=sin(x) at every point where the rate of ...
