WebSimplify tan(-1)(-( square root of 3)/3) Mathway Free math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with step-by … WebAug 13, 2016 · sec−1(2) = π 3 Explanation: Let the answer be x. Since sec−1(2) = x, sec(x) = 2. As secant is the reciprocal of the cosine function, i.e. sec(x) = 1 cos(x), the following must be true as well. 1 cos(x) = 2 Or cos(x) = 1 2. The range of sec−1(x) is [0, π 2) ∪ ( π 2,π]. The range of cos−1(x) is [0,π]. Since the ranges are similar, we can find x using black woman good morning emoji
