COTH(z)
- where z is any real number
Description
- This function gives the hyperbolic Cotangent of 'z'.
- It's also called as Circular function.
- COTH is the reciprocal of TANH function.
- i.e or Icot(iz).where 'I' is the imginary unit and i=sqrt(-1).
- Also relation between Hyperbolic & Trignometric function is
- cot(iz)=-icothz&coth(iz)=-icot z
i.e 
or Icot(iz).where 'I' is the imginary unit and i=sqrt(-1).Examples
COTH(z)
- z is any real number.
| COTH(z) | Value(Radian) |
| COTH(1) | 1.3130352854993312 |
| COTH(30) | 1 |
| COTH(-45) | -1 |
