How This Converter Works
Calculates cotangent for an input angle, in degrees by default or radians when selected. Blank input clears the output, non-finite input shows Invalid input, and values with sine magnitude below 1e-12 show Undefined. Other results use exactly 12 decimal places.
Formula or rule
cot(x) = cos(x) / sin(x), with degree inputs first converted by x * pi / 180
Example
- Input
- 45 degrees
- Calculation
- cos(45 * pi / 180) / sin(45 * pi / 180)
- Result
- 1.000000000000
