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 or , where is the imaginary unit and
- Also relation between Hyperbolic & Trigonometric function is &
- COSH(-z) = COSH(z)
or 
, where 
is the imaginary unit and 
& 
Examples
COSH(z)
