COSH(z)

• where z is any real number

Description

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

Examples

COSH(z)

• z is any real number.
