COSH(z)

This function gives the hyperbolic Cos of 'z'.
Also it is called as Circular function.
Here $COSH={\frac {e^{z}-e^{-z}}{2}}$ or $-iSIN(iz)$ , where $i$ is the imginary unit and $i={\sqrt {-1}}$
Also relation between Hyperbolic & Trigonometric function is $Sin(iz)=iSin(hz)$ & $Sinh(iz)=iSin(z)$
COSH(-z)=COSH(z)
