Hey,

I am trying to approximate the solution to a second order ODE using the 4th order Runge-Kutta.

I was told that in order to do this, I have to write the second order ODE and a pair of 1st order ODEs.

Given that my differential equation is

d^2v/dt^2 + adv/dt + bv = 0, where a and b are constant coefficients, I am a little lost on how to do this.

Any advice on how to approach this?

Thanks
