WebNov 6, 2015 · Find tan 2x knowing sin x = -3/5 and 180 < x < 270. Ans: 24/7 sin x = - 3/5. First, find cos x. cos^2 x = 1 - sin^2 x = 1 - 9/25 = 16/25 --> cos x = +- 4/5. Since arc x is located in Quadrant III, then both sin x and cos x are negative --> cos x = -4/5. sin 2x = 2sin x.cos x = 2(-3/5)(-4/5)= 24/25 cos 2x = 1 - 2sin^2 x = 1 - 18/25 = 7/25 tan 2x = (sin … WebSymbolab is the best step by step calculator for a wide range of math problems, from basic arithmetic to advanced calculus and linear algebra.
