Math.Tanh Method (Double)


Returns the hyperbolic tangent of the specified angle.

Namespace:   System
Assembly:  mscorlib (in mscorlib.dll)

static member Tanh : 
        value:float -> float


Type: System.Double

An angle, measured in radians.

Return Value

Type: System.Double

The hyperbolic tangent of value. If value is equal to NegativeInfinity, this method returns -1. If value is equal to PositiveInfinity, this method returns 1. If value is equal to NaN, this method returns NaN.

The angle, value, must be in radians. Multiply by Math.PI/180 to convert degrees to radians.

The following example uses Tanh to evaluate certain hyperbolic tangent identities for selected values.
