What’s a double integral? (I may know how to do them but not recognize the name so clarify por favor
If you dislike math homework...

Double integral is used to find the area of something that has two variables, usually under a curve.

Also, this should really be more of a tutoring thing. You give them the answers, they won’t know what to do when they have to do it themselves
Send it to me here and I'll dm you all the answers. I'll take anything below double integrals.
