### 構文

IMCOS("複素数")

Complex_number is a complex number whose cotangent is to be calculated.

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.

### 例

=IMCOT("4-3i")
は0.00490118239430447+0.999266927805902iを返します。

=IMCOT(2)
は-0.457657554360286を文字列として返します。The imaginary part is equal to zero, so it is not displayed in the result.
