Below is an inverse cotangent calculator (or arccot calculator), which calculates an angle from the ratio from the cotangent function. Enter a result and choose to return radians or degrees, then compute the angle.
Inverse Cotangent Calculator
Using the Arccotangent Calculator
To use the tool to find the angle from a known cotangent, enter the ratio and the units you'd like and compute.
- Cotangent - ratio of the adjacent side to the opposite side
- Output Degrees or Radians? - choose to return degrees or radians
Once you're happy, click the "Compute Arccot" button.
- Angle - the input angle if you wanted to get the cotangent you entered
What is the arccotangent or inverse cotangent?
Arccotangent is the inverse of the cotangent, which is the ratio of the adjacent side to the opposite side in a right triangle.
Arccotangent as a formula
Inverse cotangent is usually abbreviated as "arccot" or "acot", as in the following equation:
Where it is the inverse of cotangent, or:
