1. The problem statement, all variables and given/known data I'm not sure if this is pre calculus or calculus and beyond. If I've posted in the wrong section, please feel free to move this topic. ∫t2 * lnt dt 2. Relevant equations 3. The attempt at a solution I've tried using the integration by parts: ∫uv' dt = uv - ∫u'v dt u = lnt u' = 1/t v = t3 / 3 v' = t2 I then get the following: lnt * t3 / 3 - ∫1/t * t3 / 3 I'm not sure where to continue from this.
