Integration problem: If I Integrate this $\ \int\frac{y}{(y+1)^2}dy$ using integration by parts I get:$\frac{-y}{y+1}+ln(y+1)$ but if I do this: $\ \int\frac{y}{(y+1)^2}dy$ $\ \int\frac{y+1}{(y+1)^2} -\frac{1}{(y+1)^2}dy$and integrate I get $\ \frac{1}{y+1} +ln(y+1)$ Sooo, what did I do wrong, what am I missing?
