[QUOTE="Hiero, post: 6391143, member: 602040"] Thank you [USER=43978]@Dale[/USER], though I’m still not sure if I’m correct. I can manipulate mine to look exactly like their version (which is just the first term) [I]except[/I] where they have ##(1-\vec \beta \cdot \hat n)^3## in the denominator, I instead have ##(1-\beta ^2 - (\vec \beta \cdot \hat n)^2)^{3/2}## I thought this meant I was wrong until I noticed the little sub t_r on their parenthesis indicating that they’re evaluating it at the retarded time whereas I’m using the instantaneous displacement, so my {[B]n[/B], |[B]r[/B]-[B]r[/B][SUB]s[/SUB]|} is not the same as theirs. I suspect mine is still right because they show the same retarded denominator for the electric field, and my instantaneous denominator is the same as I saw for the electric field of a uniformly moving charge in Purcell’s book, but I’ll have to wait until tomorrow to think about it and be sure.
