find the integral of (cosx)^2(tanx)^3
so first of all i rewrote tan to be (sinx)^3/(cosx)^3 so that i could cancle out the (cosx)^2 on top
and now i have the integral of (1/cosx)(sinx)^3
i rewrote that to be (tanx)(sinx)^2...and now i am stuck
i don't know of any IDs that could make the integral simplier...i am open to suggestions
