Returns the hyperbolic cosine of the specified complex number.

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

static member Cosh : 
        value:Complex -> Complex 

Parameters

value
Type: System.Numerics.Complex
A complex number.

Return Value

Type: System.Numerics.Complex
The hyperbolic cosine of value.

The Cosh method for complex numbers corresponds to the Math.Cosh method for real numbers.

The Cosh method uses the following formula to calculate the hyperbolic cosine of the complex number a + bi:

(Cosh(a) * Cos(b), Sinh(a) * Sin(b))
