wait, thats not the same second derivative as I got... I don't see how you got that second term. Mine was more complicated.

(note that we have a product of functions-- is a function as well as , hence we need the product rule, which yields two terms)
oh i see now, I treated as a term rather than a constant. This makes things much easier, thanks!
