It is not my problem that you had so much trouble with getting a few basic derivatives correct <shrug>. So many errors in your math makes it so painful teaching you.
I admitted in that thread that I am not a mathematician and my calculus is lousy. Maybe you get a kick out of getting me to say that again and again. Your calculus might be good, but you are lousy at understanding the physical interpretation of the equations.

We did this calculation in my GR class last semester. It took me a bit of time to find my book, but as I suspected (the answer is given on p.261 of Hartle with other relevant formulas scattered throughout the chapters), every formula that you wrote is exactly correct.
Thanks Luke
