Hello I am little bit confused about lagrange approximation to geodesic equation:(adsbygoogle = window.adsbygoogle || []).push({});

So we have lagrange equal to L=g_{μν}d/dx^{μ}d/dx^{ν}

And we have Euler-Lagrange equation:∂L/∂x_{μ}-d/dt ∂/∂x(dot)_{μ}=0

And x(dot)_{μ}=dx_{μ}/dτ. How do I find the value of x(dot)_{μ}?
