The Excel SINH Function

Hyperbolic Functions

The basic hyperbolic functions, cosh, sinh and tanh are related to the equilateral hyperbola, x2-y2=1.

If the area between a line through the origin, the x-axis, and the hyperbola x2-y2=1 has area α/2, then:

  • cosh α is the x-coordinate of the intersection between the line through the origin and the hyperbola x2-y2=1
  • sinh α is the y-coordinate of the intersection between the line through the origin and the hyperbola x2-y2=1
  • tanh α is equal to sinh α / cosh α

Sinh Function Error

If you get an error from the Excel Sinh Function, this is likely to be the #VALUE! error:

Common Error
#VALUE! - Occurs if the supplied number argument is not recognized as a numeric value.
