# integral de x 3 cos 3x dx

Use integration by parts with u ln x, du x1 dx, dv x3 dx and v (1/4) x4. You get t0 1 cos t. The rst two limits here are a 0/0 indeterminate form (which I would expect you to indicate with your solution) the third is evalutated by simply plugging in t 0 For the second integral, use u sin(x), du cos(x)dx.For the rst integral, use x 2 tan(t) or the formula from section 6.8.
