Hi, I'm trying to understand point charges along a uniformly charged line with a charge per unit length. This is a screenshot of what I'm trying to understand. http://i.imgur.com/s1vX7.jpg
I am not sure where the term r/R is coming from. I realize that the r term in sigma*dx/4pi*enot should...
I'll look over the telescoping series and read over that section again later.
yeah I knew that integral but on that page it just appears with that inequality. he doesn't develop n^3/3 it just appears at that moment. I think I understand the rest of the proof though. I just was confused about...
Hi, I'm curious in learning calculus again but through a more rigorous fashion than plug and chug that I did last year.
I'm trying to go slowly through Apostol's calculus but the way he's deriving the integral for a parabolic function x^2 is kinda troubling me.
I'm fine until he reaches...
