COSH(Number)

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