COTH(number)
number
The value for which you want the hyperbolic cotangent. For example: 1, -0.5, A1. Cannot be 0.
More details
COTH calculates the hyperbolic cotangent, which equals 1/TANH(number) or (EXP(number) + EXP(-number))/(EXP(number) - EXP(-number)). Returns #DIV/0! error when the input is 0. For large absolute values, approaches ±1.
