Hi, guys. For an E&M/quantum mechanics problem I have to integrate the series below: Homework Statement Integrate \int{r^{2}e^{y r} \, dr}.2. The attempt at a solution Using integration by parts and and "differentiating under the integral" give the same answer: I= \frac{2...

Yeah, you get this result with integration "by parts", which is the name for using the product rule to rewrite integrals (hopefully in a form you can recognize and solve). If you take a second-semester single-variable calculus class you'll learn about this.
