@Signus: I've been working through your solution (finally I know all the prereqs, I think) and I'm relatively sure you messed up taking $\delta^{(1)} F_c$. But I could be wrong. I don't think there should be a square on the second $(2H+c_0)$. Am I right? If not, why is there a square there?

This is close to what I needed, but was insanely confusing because before yesterday I didn't know what a Christoffel symbol was, let alone all of their crazy definitions. Looking back on it now, if I'd been up to speed on all my prereqs for this question, that would have been really useful. Thanks!

Found it, it's being sent from another library and should be mine within 7 business days :). I didn't even know you could do that, thanks for the suggestion!

How did you derive $\delta^{(1)}H$?

Yes, I think so. Thank you!

So, basically $\Psi \sim z(u,v)$? I have to say, I don't really see the point in that, and it doesn't realllyyy tell me what $\psi$ is either.... Also, I'll go into the library and ask tomorrow, good idea!

Thank you!! Do you have any idea where I might find this book online? I'm an undergrad and definitely don't have 77$ to spend on it...

@Signus Do you own the book, or have a link to where I can find it? Google preview doesn't show page 67 so I'm still lost as to $\psi$. :(

@Signus Don't worry about the $g$s, I've been reading that book and fully understand them now. Thank you for that reference. Google preview only goes up to page 47, but that seems like it's good enough... Is $\psi$ the inclination angle talked about on page 42?

@Signus This is great, thank you so much! I'm a little confused about the meaning of $\psi$. Also, what are all the $g$s?
