👉 Cotane, in mathematical terms, is a function that takes two arguments and returns their ratio. Specifically, it's defined as: \[ \cot(x) = \frac{1}{\tan(x)} \] Here, \( \tan(x) \) represents the tangent of an angle measured from the positive x-axis to the point on the unit circle at which the angle is located. Therefore, cotane is a function that calculates the ratio between two angles.
