Returns the inverse cotangent (the arccotangent) of a number. This function calculates the principal value.
This function returns the inverse trigonometric cotangent of Number, that is the angle (in radians) whose cotangent is Number. The angle returned is between 0 and PI, i.e. [0, π].
Number is the real number, or a reference to a cell containing that number, whose inverse trigonometric cotangent value is to be calculated.
- To return the angle in degrees, use the DEGREES function.
- Alternatively multiply by 180/PI() to convert the result from radians to degrees.
