SINH()
Hyperbolic Sine of the argument
Syntax
SINH( nArea ) -> nHyperbolicSine
Arguments
<nArea> the size of the area (see below)
Returns
<nHyperbolicSine> the hyperbolic sine of <nArea>
Description
The function SINH() calculates the hyperbolic sine of the argument. In analytical mathematics it is defined as 1/2*(exp(nArea)-exp(-nArea)). A common geometric interpretation of the SINH() function is the maximum y value of the points in the area with the given size <nArea>, that is bound by the x axis, a straight line through the point of origin (this one is fixed by the area) and the hyperbola xˆ2-yˆ2=1.
Examples
? sinh( 0.0 ) // --> 0.0
? sinh( 1.0 ) // --> 1.1752...
Tests
sinh( 0.0 ) == 0.0
sinh( -0.5 ) == -sinh( 0.5 )
