The derivative of sinh x is cosh x and the derivative of cosh x is sinh x; this is similar to trigonometric functions, albeit the sign is different (i.e., the derivative of cos x is −sin x). The Gudermannian function gives a direct relationship between the circular functions and the hyperbolic ones that does not involve complex numbers. To begin, we present a program that simply calls Acos, Cos, Cosh, Asin, Sin, Sinh, Atan, Tan and Tanh. All of these methods receive arguments in units of radians represented by the double type.
