ACOT

ACOT(number)

Returns the angle in radians for a given cotangent ratio.

number

The cotangent ratio.

REMARKS

* For an illustrated example refer to the Trigonometric Functions page.
* The angle returned is in radians between 0 and PI.
* If "number" is not numeric, then #VALUE is returned.
* To convert a number from degrees to radians, multiply it by PI/180
* To convert a number from radians to degrees, multiply it by 180/PI.
* You can use the COT function to return the cotangent ratio of an angle.
* You can use the ACOS function to return the angle in radians for a given cosine ratio.
* You can use the ASIN function to return the angle in radians for a given sine ratio.
* You can use the ATAN function to return the angle in radians for a given tangent ratio.
* You can use the RADIANS function to convert from degrees to radians.
* You can use the DEGREES function to convert from radians to degrees.
* You can use the TAN function to return the tangent ratio of an angle.
* You can use the ATAN2 function to return the arc-tangent of the given x and y co-ordinates.
* You can use the IMCOS function to return the cosine ratio of a complex number.
* This function was added in Excel 2013.
