This is not homework, but rather me just trying to work a numerical analysis problem.(adsbygoogle = window.adsbygoogle || []).push({});

I have a second order equation on the form m*y'' = a*y + n*x (no first derivative)

How does one convert this? It's been years since I did this. Last I remember, one would start with substituting the first derivative with something. (u = y'), but now there's no such part in the equation.

Thanks!
