Frustration

I am finding the latest Q Phys assignment enormously frustrating. While I am willing to put hours and hours into a lab report, I just can't quite bring myself to care about this homework. There are five questions and four of them require a derivation at some point. For god's sake, it is really necessary to make us re-derive these equations? I can't get half of them, and it has made me unreasonably angry.

I hate engineering. I want out. Immediately.
