Use the given information to find the values of sin 2theta. cos2theta. and tan 2theta. Sin theta = -15/17; The terminal side of theta lies in quadrant III.sin 2theta = (Simplify sour answer, including any radicals. Use integers or fractions for any numbers in the expression) cos2theta = Square (Simplify sour answer, including any radicals. Use integers or fractions for any numbers in the expression) tan 2 theta =Square (Simplify sour answer, including any radicals. Use integers or fractions for any numbers in the expression) Solution sin = -15/17 is in QIII now by sin^2 +cos^2 =1 cos^2 = 1- (-15/17)^2 cos = -8/17 so now sin2 =2sin.cos = 2(-15/17) .(-8/17) = 240/289 cos2 =cos^2 -sin^2 = (-8/17)^2 - (-15/17)^2 =64/289 - 225/289 = -161/289 tan(2) = sin2/cos = 240/-161 = -240/161.
