Derivatives v t e In mathematics, the inverse trigonometric functions (occasionally also called arcus functions, [1] [2] [3] [4] [5] antitrigonometric functions [6] or cyclometric functions [7] [8] [9]) are the inverse functions of the trigonometric functions (with suitably restricted domains ). Most calculators use the (confusing) notation: `sin^-1 x`. One way to do this that is particularly helpful in understanding how these derivatives are obtained is to use a combination of implicit differentiation and right triangles.
