'''Cotangent''' is a [[trigonometry|trigononmetric]] function describing the ratio of the adjacent side to the opposite side in a right triangle.

'''Cotangent''' is a [[trigononmetric function]] describing the ratio of the adjacent side to the opposite side in a [[right triangle]]. It is often abbreviated ''cotan''.

<math>\cot \theta = \frac{\cos \theta}{\sin \theta} = \tan \left(\frac{\pi}{2} - \theta \right) = \frac{1}{\tan \theta} \,</math>
