\question[10]
\label{Q:zbus}
Prove that necessary conditions for the curve $u = u(t), v = v(t)$ on a surface $\vec(r) = \vec(r)(u,v)$ to be geodesic is that \begin{equation}U \frac{\partial T}{\partial \dot{v}} - V \frac{\partial T}{\partial \dot{u}}\end{equation}
where
$$ U = \frac{d}{dt} \Big(\frac{\partial T}{\partial \dot{u}}\Big) - \frac{\partial T}{\partial u} = \frac{1}{2T}\frac{dT}{dt}\frac{\partial T}{\partial \dot{u}}$$
$$ V = \frac{d}{dt} \Big(\frac{\partial T}{\partial \dot{v}}\Big) - \frac{\partial T}{\partial v} = \frac{1}{2T}\frac{dT}{dt}\frac{\partial T}{\partial \dot{v}}$$
