    3.6 Exercises

    Exercise \(\PageIndex{1}-\PageIndex{4}\)

    In problems 1–4, a function \(u\) or \(dv\) is given. Find the piece \(u\) or \(dv\) which is not given, calculate \(du\) and \(v\), and apply the Integration by Parts Formula.

    3. \(\int x^4 \ln(x) dx\) \(dv = x^4 dx\) 4. \(\int x \cdot (5x + 1)^{19} dx\) \(u = x\)
