The COSH function returns the hyperbolic cosine of a number.

This function takes a single Number as input. It outputs that Number's hyperbolic cosine.


COSH(number) -> hyperbolic_cosine



number (required, type: Number)
The number to calculate the hyperbolic cosine of.

Return Values

hyperbolic_cosine (type: Number)
The hyperbolic cosine of the given number.


The following example returns the hyperbolic cosine of 1:

COSH(1) -> 1.5430806348152437
