COSH(Number)

• Number is any real number.
  • COSH() returns the hyperbolic cosine of a number.

Description

• 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)

Examples

COSH(z)

• z is any real number.

COSH(z)	Value
COSH(0)	1
COSH(10)	11013.232920103319
COSH(7)	548.3170352
