COTH(Number) Function
Calculates the hyperbolic cotangent of
argument “Number”. This function returns a number greater than or equal to 1, or
less than or equal to -1. The argument “Number” can take a non-zero numeric
value. The hyperbolic cotangent presents a discontinuity at 0. For example:
=COTH(0,5) Returns 2,164.
=COTH(2) Returns 1,037.
