Is someone able to show me how I'd calculate this integral (showing working steps)? Any help would be greatly appreciate.

Yeah, I think I'm okay from there. I knew there was a way to simplify the integral, but I just couldn't see it. Been doing this for too long tonight! Thanks.
Actually, something I'm confused about. Why did you bother making the equation: rather than just: Wouldn't the second option be equal, but easier to solve?

Let's focus on . Let and Then and Thus, . Now, note that So you'll end up with the same thing! I just thought forcing product rule in the integrand would save time in integrating ==> you only need to apply integration by parts twice.
