COSH function

The COSH function returns the hyperbolic cosine of the required argument, where the argument is an angle expressed in radians.

COSH function

1  COSH ( radian_expr )
Element Description Restrictions Syntax
radian_expr Expression that evaluates to an angular value in units of radians Must be of a numeric data type Expression
The following example returns the hyperbolic cosine of the values in the degrees column of the anglestbl table. The expression passed to the COSH function converts the degrees to radians.
SELECT COSH(degrees*180/3.1416) FROM anglestbl;
