Hi , everyone(adsbygoogle = window.adsbygoogle || []).push({});

I have a problem with geodesic equation .

I know the method of solving it , but I can't understand the solutions .

When I tried to solve it for a torus I arrived at :

[tex]\dot{u}

= \frac{k}

{{\left( {c + a\cos v} \right)^2 }}

\][/tex]

[tex]\[

\dot v = \pm \sqrt { - \frac{{k^2 }}

{{a^2 \left( {c + a\cos v} \right)^2 }} + l}

\][/tex]

c is the major raduis and a in the minor raduis .

What dose this mean ?

Thanks .
