The basic hyperbolic functions, cosh, sinh and tanh are related to the equilateral hyperbola, x^{2}y^{2}=1.
If the area between a line through the origin, the xaxis, and the hyperbola x^{2}y^{2}=1 has area α/2, then:
The equation used to calculate the hyperbolic sine is:
The Excel Sinh function calculates the hyperbolic sine (sinh) of a supplied number.
The syntax of the function is:
Where the number argument is a real number that you want to calculate the hyperbolic sine of.
The following spreadsheet shows the Excel Sinh Function, used to calculate the hyperbolic sine of three different values:

If you get an error from the Excel Sinh Function, this is likely to be the #VALUE! error:
#VALUE!    Occurs if the supplied number argument is not recognized as a numeric value.
