Runge-Kutta problem

Hey all!

I'm trying to use the Runge-Kutta method on this differential equation but I am getting nowhere and it's starting to confuse me :S

Any help would be greatly appreciated!


[tex] \frac{dx_{1}}{dt} = g_{2} \frac{y_{2} - y_{1}}{{|r_{2} - r_{1}|}^2} [/tex]

Give us a clue: tell us how [TEX]{y}_{1}[/TEX], [TEX]y_2[/TEX], [TEX]r_1[/TEX], [TEX]r_2[/TEX], and [TEX]g_2[/TEX] depend on [TEX]x_1[/TEX] and [TEX]t[/TEX].

(If they were all constants, the solution is rather trivial!)

In addition to AlephZero's question, is there a simultaneous equation for dx2/dt ? (If not, why is there subscript on x?)
