Using the hyperbolic functions
The Hyperbolic list contains the following functions:
Function Abbreviation Description
Hyperbolic cosine CosH(x) Returns the hyperbolic cosine of x
Hyperbolic sine SinH(x) Returns the hyperbolic sine of x
Hyperbolic tangent TanH(x) Returns the hyperbolic tangent of x
Hyperbolic arc cosine ArcCosH(x) Returns the inverse hyperbolic cosine of x
Hyperbolic arc sine ArcSinH(x) Returns the inverse hyperbolic sine of x
Hyperbolic arc tangent ArcTanH(x) Returns the inverse hyperbolic tangent of x
Examples
y(x) = sinh(4x)*cosh(2x)
y(x) = tanh(sin(x))
y(x) = x*arcsinh(2x)
