I m having a difficult time solving this integral I tried integrating by parts sin2xcos4xdx u sin2x dv cos4xdx I used the power reducing formula to evaluate sin2x Solution steps cos4 x sin2 x dx Rewrite using trig identities cos4 x 1 cos2 x dx Expand cos4 x 1 cos2 x cos4 x cos6 x cos4 x cos6 x dx Apply the Sum Rule f

First you can rewrite sin 4x as either 1 cos 2x 2 or dfrac 1 cos2x 2 2 You seem to have crossed up both The second problem is if you try the substitution u cos x du sin Setting u sin x dv cos4 x sin x dx we get sin2 x cos4 x dx sin x cos5 x 5 1 5 cos6 x dx which certainly doesn t look any better but we can take two cosines from the six
