{{DavinciWiki_Function|
Computes the trigonometric cotangent of the input value.
|
Parameters: An array of any numeric data type or organization containing the values of angles in radians.

Return Value: A float array of the same organization as the input containing the cotangent of the input.
|
[[Syntax]]: cot(x)

'x' is any numeric array

This function just uses cot(x) &#61; 1/tan(x); it will print a divide by zero warning (and return the correct value, 0) when x &#61; 0

Cotangent is undefined (infinite) for x &#61; n*&pi; for any integer n; this function returns zero in those cases

Return format is double if input is double; float otherwise

When cot() is entered without any arguments, it prints its description, as shown below.
