Web8 Dec 2024 · Secant is the reciprocal of the cosine. It's the ratio of the hypotenuse to the adjacent. The abbreviation of secant is sec, e.g., sec(30°) and it's range is sec(α)≥ 1 and sec(α) ≤ -1: sec(α) = 1 / cos(α) = c / b. Cotangent is the reciprocal of the tangent. It's the ratio of the adjacent to the opposite side.
