Tag: ATAN function

The ATAN function is a mathematical function that returns the arctangent of a given angle in radians. The arctangent is the angle whose tangent is a given number. In other words, if you know the tangent of an angle, you can use the ATAN function to find the angle itself.

The input for the ATAN function is a number or a reference to a cell containing a number. The output is the angle in radians.
