rmc240 said:I'm reading a derivation and it says that the following approximation can be used:
I do not under stand how Taylor's theorem allows for this approximation. Can anyone explain this a little?
If you let ##f(r) = \frac{dv}{dr}## you have ##f(r+dr) = f(r) + f'(r)dr##. Do you recognize that?

Yea, my problem was realizing that I was supposed to approximate the function around r and evaluate the function at r + dr. Should have seen that. Thank you for your help.
