In fact, you Nov 01, 2012 · Lol, I did your cos^4/sin^6 question!! Given that cos x/sin x = cot x. Differentiate cot x = -cosec^2 x ! ( cosec^2x = 1/sin^2x) So given this let U= cot x du= -cosec^2x dx 4 2 1 − 2 cos(2x) + cos2(2x) + cos(2x) − 2 cos2(2x) + cos3(2x) = 8 1 − cos(2x) − cos2(2x) + 3cos (2x) = 8 This is all the side work we need to do here, because we know that: cos 2 (2x) = x + sin(2x) + c 1 and 2 4 cos 3 (2x) = 1 sin(2x) − 1 sin3(2x) + c 2.
