      The derivative of y=sin(x) is y’=cos(x), and the derivative of y=sin(2x) is y’=2*cos(2x). 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 ...

      Let's see why some of . Proposition 1. Show that = = Proof. Let y = sin-1x so that x = sin y. Use implicit differentiation. Take the derivative of both sides of this last formula with respect to x to get 1 = (cos y) . Thus = = = which proves the sin-1 formula. The cos-1 follows from the sin-1 formula and cos-1x = - sin …
