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.COTH(z)=
- i.e or iCOT(iz).where 'i' is the imaginary unit and .
- Also relation between Hyperbolic & Trignometric function is &
i.e 
or iCOT(iz).where 'i' is the imaginary unit and 
.
& 
Examples
COTH(z)
- z is any real number.
