COSH(Number) Function
Calculates the hyperbolic cosine of argument “Number”. This function returns a numeric value. The argument “Number” is any positive, numeric value, negative or zero. The hyperbolic cosine is a continuos function, therefore, can take any numerical value. However, if the argument is a very big value, possibily, the function returns the error value #NUM!, indicated that it has exceeded the computational power of computers. Similarly, if the argument is a ver small negative number, for example, -3000, may return the same error message because the result is great. For example:

=COSH(0) Returns 1.
=COSH(-1) Returns 1,543.
=COSH(1) Returns 1,543.
