Can Maple's dchange command (PDEtools) implement the following change of
variables:
y"(t) -> v'(y) v(y)
where v = y'(t).
If so, how?
I could never figure out how to make this common transformation
(physics, dynamics, mechanics,...) with the now obsolete Dchangevar
command (DEtools) and I still haven't figured out how to do it with
dchange.
