For those who don't have the book, what I want is to get this equation:
from this one:
My problem is how to get the first term (in front of the first integral), only by expanding the (1-2GM/rc^2) in powers of 1/c^2. Someone?
Hi everyone!
I was trying to solve this question following the Hartle's book (Gravity: an introduction to Einstein’s general relativity) , exercise 9.15, but I don't know how to do the expansion of (1-2GM/c^2r) in powers of 1/c^2...
I know this sounds easy, but I couldn't get the expression...
