COSH

The COSH function computes the hyperbolic cosine of an expression a. COSH(a) = (ea + e-a) / 2.0

Format

COSH(a)

Arguments

 
a
Any valid function expression.
Number of Arguments: 1

Examples

REQUEST/36,
, F2=COSH(DZ(21,11,11))
This REQUEST statement returns the hyperbolic cosine of the z-component of the displacement of Marker 21 with respect to Marker 11 in its second column. The result is computed in the coordinate system of Marker 11.
