= x5 5 × lnx −∫ x5 5 × dx x.
For teachers for schools for working scholars® for. Either way i am stuck here. $\begingroup$ @ron you directed me to your post, so i hope you're willing to answer some of my questions. First, we must identify a section within the integral with a new variable (let's call it u), which when substituted makes the integral easier.
= lnx ×x5 5 − 1 5∫x4dx.
