COT

COT(number)

Returns the cotangent of a number.

number

The number you want the cotangent of.

REMARKS

* For an illustrated example refer to the [[Trigonometric Functions]] page.
* 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.
* This function was added in Excel 2013.
