Rate of change of a variable y is proportional to the value of y. However, in the following list, each trigonometry function is listed with an appropriately restricted domain, which makes it onetoone. Each of the six basic trigonometric functions have corresponding inverse functions when appropriate restrictions are placed on the domain of the original functions. So that would be f inverse, or were saying g is the same thing as f inverse. It follows that a function that has a continuous derivative has an inverse in a neighbourhood of every point where the derivative is nonzero.
