COSH

Returns the hyperbolic cosine of the argument; the argument is expected in radians.

Syntax

COSH(expr)

Argument

expr: An argument as a real number or another data type that can be converted into a numeric data type representing the radians.

Example

SELECT 0 as Angle, 0 as expr, cosh(0) as "cosh(expr)"
UNION ALL 
SELECT 180 as Angle, 3.14 as expr, cosh(3.14) as "cosh(expr)"
UNION ALL 
SELECT 180 as Angle, 3.14 as expr, cosh('3.14') as "cosh(expr)" 
UNION ALL 
SELECT 90 as Angle, 1.57 as expr, cosh(1.57) as "cosh(expr)"
UNION ALL 
SELECT 270 as Angle, 4.71 as expr, cosh(4.71) as "cosh(expr)"
;
