COT(number) Function
Calculates the cotangent of the argument “number”.
This function returns a numeric value negative, positive or zero. The cotangent
is a discontinuos function, therefore, there are values for which the cotangent
is not defined. When yoy generate the graph of the cotangent function, you must
select the range indicated for not getting erroneos results. For example:
=COT(PI()/2) Returns 0.
=COT(-PI()/2) Returns 0.
=COT(0,5) Returns 1,83.
