👉 The term "cotangent" is a mathematical concept that refers to the ratio of the adjacent side to the opposite side in a right triangle. It is often used in trigonometry and geometry, particularly when dealing with triangles or circular shapes. The cotangent function is defined as: \[ \cot(x) = \frac{\text{opposite}}{\text{adjacent}} \] Where x represents an angle in radians or degrees. This definition can be useful in solving problems involving right-
