COTH(x)

• where x is any real number.
• COTH() returns the inverse hyperbolic tangent of a number.

## Description

• This function gives the hyperbolic Cotangent of 'x'.
• It's also called as Circular function.
• Let z is any real number.
• 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 &
