Arccosec Inverse cosecant Is Derived by: Atn(A / Sqr(A * A -1)) + (Sgn(A) - 1) * (2 * Atn(1)). HCos Hyperbolic cosine Is Derived by: (Exp(A) + Exp(-A)) / 2. HSin Hyperbolic sine Is Derived by: (Exp(A) - Exp(-A)) / 2. HTan Hyperbolic tangent Is Derived by: (Exp(A) - Exp(-A)) / (Exp(A) + Exp(-A)). HCotan Hyperbolic cotangent Is Derived by: (Exp(A) + Exp(-A)) / (Exp(A) - Exp(-A)). HSec Hyperbolic secant Is Derived by: 2 / (Exp(A) + Exp(-A)). HCosec Hyperbolic cosecant Is Derived by: 2 / (Exp(A) + Exp(-A)). HArccos Inverse hyperbolic cosine Is Derived by: Log(A + Sqr(A * A - 1)). HArcsin Inverse hyperbolic sine Is Derived by: Log(A + Sqr(A * A + 1)). HArctan Inverse hyperbolic tangent Is Derived by: Log((1 + A) / (1 - A)) / 2. HArcsec Inverse hyperbolic secant Is Derived by: Log((Sqr(-A * A + 1) + 1)) / A. HArccosec Inverse hyperbolic cosecant Is Derived by: Log((Sgn(A) * Sqr(A * A + 1) + 1) / A. HArccotan Inverse hyperbolic tangent Is Derived by: Log((A + 1) / (A - 1)) / 2. Exp Exponential Raise the natural logarithm to the specified power. (Natural logarithms use a base value of approximately 2.71828182845905, normally referred to as e.) Log Logarithm Return the exponential power for the natural logarithm. (Natural logarithms use a base value of approximately 2.71828182845905, normally referred to as e.) Log 10 Logarithm base 10 Return the exponential power for the natural logarithm base value 10. (Natural logarithms use a base value of approximately 2.71828182845905, normally referred to as e.) Sqr Square root Determine the square root of a numeric expression. Sgn Sign Determine the sign of a numeric expression. (The Sgn() function allows you to determine whether a variable contains a positive, negative or zero value. The Sgn() function returns a value of 1, -1 or 0.)      ©1997 - 1997 Erik Østergaard, Copenhagen, Denmark.
