 number The number you want the cotangent of.

 REMARKS
 * Added in Excel 2013.* The inverse of this function is the ACOT function.* The "number" is the angle in radians.* If "number" is not numeric, then #VALUE is returned.* If "number" is zero, then #DIV/0! is returned.* If "number" < -2 E10, then #NUM is returned.* If "number" > 2 E10, then #NUM is returned.* If your argument is in degrees, multiply it by PI/180 to convert it to radians.* You can use the CSC function to cosecant.* You can use the DEGREES function to convert from radians to degrees.* You can use the RADIANS function to convert from degreed to radians.* You can use the SEC function to secant.* For a working example refer to the Quant > Trigonometric Functions page.* For the Microsoft documentation refer to support.microsoft.com
