Mate I haven't even gotten to second order differentials and you're tagging me in a third order differential...

Good luck to whoever does this.

I thought you did further maths.

I did but we didn't do FP3 in which second order differentials are covered. I'm self-teaching myself that over this summer but haven't gotten to that yet.

Don't you need three arbitrary constants or is that only if the coefficients are constant?

Oh yeah I forgot one. Edited it now.
I think that there are three arbitrary constants for third order regardless of whether there are variable or constant coefficients.

Ah phew, all is right in the world of linear algebra again.
