We finished our final in Calc II, and now we are doing math projects to pass time until the semester ends.

As you can see, we must prove our product to be zero. Can anyone tell me if we are missing a sufficient part to really prove if they equal zero? Or just advice that could help make my little project more involved? Any help would be appreciated.
