If you$$ve gotten this far, you$$ve seen all of the problems we$$ve covered this term,

and you$$ve done a lot of algebra. You$$ve used a lot of different formulae to help

you solve the Exercise problems, but they are likely scattered throughout your notes

and homework. The purpose of this problem is two$-$fold: to remind you of what the

important relations were in this course, and to make sure you have a $$cheat sheet$$

of formulae at hand when you start ENPH$/$PHYS $345$ next term.

To that end, make up a cheat sheet where you complete all of the following relations

$($you don$$t need to derive them or show any work, I just want you to go back over

your notes and work, find them, and write them down, like you would do for a final

exam, except that we don$$t have one$)$
