Many thanks to sheldon who helped me reformulate the equations. It
turned out with the appropriate carefulness maxima could rearrange the
equations to be free of derivatives on the rhs. I think this is a case
of "you should have printed it out". Sometimes math is easier to do on
paper.
Now, here's a simpler question:
Why does "? rk" work on my machine at work (windows maxima 5.10) but
not at home (debian 5.10 with maxima-share package)
On windows it tells me about the runge kutta routine in the "dynamics"
package. But even though everything is up to date on the debian
machine, ? rk only gives me
? rk
-- System variable: tensorkill
Variable indicating if the tensor package has been initialized.
Set and used by `csetup', reset by `init_ctensor'.
