Fairly simple integral question.

Homework Statement

It should be fairly easy according to classmates, yet its definitely been a while since I've had calc.

Took a pic of the problem.

Sorry the image is a little dark, it says find the integral of the first one, by evaluating the integral of the second one. ?

The Attempt at a Solution

This isn't really a homework assignment, I have notes scattered throughout. Figured I'd post it in this section anyway, I'm really just trying to remember how to do half this stuff.

THANKS!

I'm not sure which question you wanted help on.

Do you remember how improper integrals are defined?

Try integration by parts on the first question and see if you can find a general formula for the integral?

Thanks I'll definitely check it out.

Sorry the image was a little dark, its one question. It says find the integral of the first one, by evaluating the integral of the second one. ?
