Cotangent calculator

This calculator works out the cotangent of an angle. You can enter the angle in degrees or in radians; choose the unit next to the field.

What the cotangent function is

The cotangent of an angle alpha is equal to cosine alpha divided by sine alpha, that is

$$\cot (\alpha )=\frac{\cos \alpha }{\sin \alpha }$$
