WebApr 14, 2015 · Explanation: cosA = 5 13. sin2A = 1 − cos2a = 1 − 25 169 = 144 169. sinA = ± 12 13. There are 2 opposite values of sin A, because, when cos A = 5 13, the arc (angle) A could be either in Quadrant 1 or in Quadrant 4. There are also 2 opposite values for tan A. tanA = sinA cosA = ± ( 12 13)(13 5) = ± 12 5.
