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 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)
- z is any real number.
| COSH(z) | Value |
| COSH(0) | 1 |
| COSH(10) | 11013.232920103319 |
| COSH(7) | 548.3170352 |
