## 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:

arccot(y)=acot(y)

Where it is the inverse of cotangent, or:

x=arccot(y)\\y=cot(x)
