1. The problem statement, all variables and given/known data 2. Relevant equations Shown in question. 3. The attempt at a solution So I was given this question for homework and I'm really not sure where to start. I'm not looking for somebody to do my homework for me, just somebody to point me in the right direction. The professor never went over anything like this in class or described the formula for the curve fitting to us. I have searched through my book and the internet and can not find much useful information to get me started. Any help would be appreciated. Thanks in advance.
