CSCH(z)

This function gives the Hyperbolic Cosecant of 'z'.
It's also called as Circular function.
Here $CSCH=sinh(z)^{-1}$ ie, ${\frac {2}{e^{z}-e^{-z}}}$ or $-Icsc(iz)$ , where $i$ is the imaginary unit and $i={\sqrt {-1}}$
The relation between Hyperbolic & Trigonometric function is $CSC(iz)=-ICSCh(z)$ & $Csch(iz)=-iCsc(z)$
CSCH(-z)=-CSCH(z)

SINH(z)
