Cotangent Calculator

Calculate the cotangent of a number

The calculator will find the cotangent of the given value in radians or degrees.

The cotangent $y=\cot(x)$ is such a function that $y=\frac{\cos(x)}{\sin(x)}$ .

The domain of the cotangent is $x \ne \pi n, n \in \mathbb{Z}$ , the range is $(-\infty,\infty)$ .

It is an odd function.

Find $\cot{\left(\frac{\pi}{12} \right)}$ .

$\cot{\left(\frac{\pi}{12} \right)} = \cot{\left(15^{\circ} \right)} = \sqrt{3} + 2\approx 3.732050807568877$ A
