This is not a homework question. I am doing extra work to get a grasp on integration and I am not sure if this is correct...(adsbygoogle = window.adsbygoogle || []).push({});

[tex]\int(sin^2x*cos^2x)dx[/tex]

I did this:

1) [tex]\int(sinx*cosx)*(sinx*cosx)dx[/tex]

2) [tex]\int(1 /2 sin(2x)) * (1 /2 sin(2x)) dx[/tex] (Double angle for sine formula)

3) [tex](1/4) \int(sin^2(2x))dx[/tex]

4) [tex](1/4) * (1/2) \int(1-cos2x)dx[/tex] (Reduction of square power)

5) = 1/8[x + (1/2)sin2x] + C

I am not sure if this is correct, just hoping someone could help me out a little or confirm it ^^

Cheers,

Adrian
