Hello,

I'm a Maple newbie and I am struggling to figure out how to compute the following:

1) Jacobian of a time dependent function:

For example I have a vector Phi = (x1(t),x2(t))
and I wish to compute the Jacobian of this vector with respect to x1(t) and x2(t) and I want to maintain the explicit reference to these entries as time dependent components.

What I can do:
