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 $-iSIN(iz)$, 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)

Examples

COSH(z)

• z is any real number.
