COT

For an angle in radians, its cosine divided by its sine.

Group: Math. Compatible with DAX.

Syntax

COT ( <number> )

Parameter	Type	Description
`number`	Number	An angle in radians; not 0.

Returns

Number. The cotangent of the angle: its cosine divided by its sine.

Remarks

It is 1 divided by TAN of the angle.
An angle of 0, and a blank, which counts as 0, are a division by zero and an error.
Angles are in radians. To work in degrees, wrap the angle in RADIANS first.
