Hello to everybody,(adsbygoogle = window.adsbygoogle || []).push({});

Since 3 days, I've been trying to obtain Eq. (173) from https://ned.ipac.caltech.edu/level5/Sept03/Trodden/Trodden5.html

I know I need to derivate with respect to a, but it is being impossible to obtain the final answer. Can anybody help me with a detailed derivation?

Thank you in a advance
