The tangent function (tan), is a trigonometric function that relates the ratio of the length of the side opposite a given angle in a right-angled triangle to the length of the side adjacent to that angle. The tangent function for acute angles can be viewed as the ratio of the opposite to the adjacent side of the angle.4 Ptolemy's theorem.
