derivative of sin(c x) or cos(c x)

You can specify function f to be some periodic function; you can also choose a value for parameter c [between 0.2 and 3] which is then used to define function g by g(x) = f(c x).[br][br]Explore how parameter c affects the relation between graphs of f and g [together with the relation between their derivative graphs].
