MONTH

Returns the cotangent of a complex number. The cotangent of a complex number can be expressed by:

cot(a+bi)=cos(a+bi)/sin(a+bi)

The result is presented in the string format and has the character "i" or "j" as an imaginary unit.

A complex number is a string expression resulting in the form "a+bi" or "a+bj", where a and b are numbers.
If the complex number is actually a real number (b=0), then it can be either a string expression or a number value.

The function always returns a string representing a complex number.
If the result is a complex number with one of its parts (a or b) equal to zero, that part is not displayed.

=IMCOT("4-3i")
returns 0.00490118239430447+0.999266927805902i.

=IMCOT(2)
returns -0.457657554360286 as a string. The imaginary part is equal to zero, so it is not displayed in the result.
