👉 Cotangent is a trigonometric function in mathematics that refers to the ratio of the length of the opposite side to the adjacent side in a right-angled triangle. It is denoted by "cot" or "cota" in some contexts. In simple terms, the cotangent (often written as "cot") can be defined as the reciprocal of the cosine function. The formula for the cotangent of an angle \( \theta \) in radians is: \[ \tan(\
