Function name:
COSH

Category:
Mathematical

Summary:
Calculates the hyperbolic cosine (cosh) of a hyperbolic angle expressed in radians.

Syntax:
COSH(Number)

Returns:
Returns a real number in the range [1, &infin;) that is the hyperbolic cosine of the specified hyperbolic angle.

Arguments:
Number is a real number, or a reference to a cell containing that number, that is the hyperbolic angle in radians whose hyperbolic cosine is to be calculated.


 * If Number is non-numeric, then COSH reports a #VALUE! error.

Additional details:
The formula for the hyperbolic cosine of x is: $$\cosh(x)~=~\frac{e^x+e^{-x}}{2}$$
