int (cscx)^3 = int (cscx)^2 cscx dx let u=cscx du=.... dv=(cscx)^2 dx v=int(cscx)^2 dx v=..... and next use parts rule : int(udv) = uv-int(vdu)

is there another trig identity i'm supposed to use? u-substitution isn't working

There is something of a trick to this... try \[\int \frac{ \sin(x)}{\sin^2(x) } dx\]
