This is more leaning toward a 4U question.<a href="http://www.codecogs.com/eqnedit.php?latex=Find \int cos^42x\, sin^32x\, \, dx\, \: using\, the\, subsitution\, u=cos2x" target="_blank"><img src="http://latex.codecogs.com/gif.latex?Find \int cos^42x\, sin^32x\, \, dx\, \: using\, the\, subsitution\, u=cos2x" title="Find \int cos^42x\, sin^32x\, \, dx\, \: using\, the\, subsitution\, u=cos2x" /></a>
Edit: This is at a 3U difficulty, right guys?
Alrighty then what about this:This is more leaning toward a 4U question.
A 3U human can do it...<a href="http://www.codecogs.com/eqnedit.php?latex=Find \int cos^42x\, sin^32x\, \, dx\, \: using\, the\, subsitution\, u=cos2x" target="_blank"><img src="http://latex.codecogs.com/gif.latex?Find \int cos^42x\, sin^32x\, \, dx\, \: using\, the\, subsitution\, u=cos2x" title="Find \int cos^42x\, sin^32x\, \, dx\, \: using\, the\, subsitution\, u=cos2x" /></a>

I was going to say lol, I thought of it as a 3u questionActually sorry - I didn't see that the substitution was given. It is doable by a 3U student.
doubt itIs this doable without IBP?
This.By just considering areas you wouldn't need parts.
Great question.
Nice work.
complete the squareGreat question.
Nice work.

1/5 . tan^-1 (x+5)/5?Great question.
Nice work.
