CSCH(z)
- Where z is any real number
- It is read as COSECH(z)
Description
- This function gives the Hyperbolic Cosecant of 'z'.
- It's also called as Circular function.
- Here ie, or , where is the imaginary unit and
- The relation between Hyperbolic & Trigonometric function is &
- CSCH(-z)=-CSCH(z)
ie, 
or 
, where 
is the imaginary unit and 
& 
Examples
CSCH(z)
- z is any real number.
| CSCH(z) | Value(Radian) |
| CSCH(0) | Infinity |
| CSCH(7) | 0.00182376 |
| CSCH(-2) | 0.27572056 |
