COSH

Returns the hyperbolic cosine of an expression that represents a numerical value.
COSH(x) = (ex + e-x) / 2.0Format
COSH(x)

Argument

 
x
Any valid expression that evaluates to a real number.

Example

The following function returns the hyperbolic cosine of the z component of the displacement of marker_2 with respect to marker_1. The result is computed in the coordinate system of marker_1. The location of marker_1 and marker_2 is shown in the figure below.
