In my book, having the right answer is about 1/4 of the problem. Knowing how/why is the other 75%. I've seen any number of exams where he answer was correct and the derivation was ridiculous. I always like to derive the answer using mte most basic calculations (so I don't have to carry much "baggage"). Cheers!
