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

Basic Description

The Excel SINH function calculates the hyperbolic sine (sinh) of a supplied number.

The format of the function is :

SINH( number )

Where the number argument is the real number that you want to calculate the sinh of. This can be input to the function either :

-     directly

-     as a value returned from another function or formula, or

-     as a reference to a cell containing a value
