COSH

COSH(number)

Returns the hyperbolic cosine of a number.

number

The number you want the hyperbolic cosine of.

REMARKS

* For an illustrated example refer to the [[Hyperbolic Functions]] page.
* The inverse of this function is the ACOSH function.
* The "number" is the angle in radians.
* If "number" is not numeric, then #VALUE! is returned.
* If your argument is in degrees, multiply it by PI/180 to convert it to radians.
* You can use the ACOSH function to return the inverse hyperbolic cosine.
* You can use the SECH function to return the reciprocal hyperbolic cosine (1/COSH)
* You can use the SINH function to return the hyperbolic sine.
* You can use the TANH function to return the hyperbolic tangent.
* You can use the DEGREES function to convert from radians to degrees
