WebJul 24, 2024 · Note that the above gives two possible values for sin(x), but since 0° < x < 90° (x is in the first quadrant), we choose the positive value. That is, sin(x) = 20/29. Now we see that. tan(x) = sin(x)/cos(x) = [20/29]/[21/29] tan(x) = 20/21. Now use the double angle formula for tangent. tan(2x) = 2tan(x)/[1 -tan 2 (x)] tan(2x) = 2(20/21)/[1 ...

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 … WebFree trigonometric identity calculator - verify trigonometric identities step-by-step
