Issues with predicting Mercury's Orbit

[Mathaddict809]

Greetings I have been trying to find the orbit of Mercury using the geodesic equations with the Schwarzschild Metric, more precisely I have been using the equations derived in "General Relativity, An Introduction for Physicists" by M.P. Hobson, etc, that is:
<math>\left(1-\frac{2\mu}{r}\right) \frac{dt}{d\tau} =k </math><br>
c^2

You need to use [tex]here, not <math>. I'll do that and see what it looks like, then try to answer it.

OK - what exactly is your question?
