Because the tangent function is a ratio of the sine and cosine functions, it may also be represented as tan2x = sin 2x/cos 2x. The Tan2x Formula is a double-angle identity in trigonometry. The tangent function can alternatively be written as tan2x = sin 2x/cos 2x since it is a ratio of ... Mar 12, 2025 ... ...
