i ve done part (a)
\[\int \frac{1+ln(u)}{u^2}du =>\int\frac{1}{u^{2}} +\frac{ln(u)}{u^{2}} => \int u^{-2} du + \int ln(u)*u^{-2} dx \] Maybe..integration by parts.
its written hence evaluate, so integrate, e^(-x)(2+x)dx by parts.
lol, yeah..i skipped that part..but its still doable from what i wrote..
