# Integration watch

1. Show that the substitution u=e^x converts the integral of (2+ln(u))/u^2 du into the integral of (2+x)/e^x dx. Hence evaluate integral of (2+ln(u)/u^2) du ?? How do you do this? I have done the first part but I don't know how to integrate after that.

Well you can split and hence integrate each one. The second one would require integration by parts.
