Hello
Would somebody direct me to a book or a place where the following is,
perhaps, addressed. I would like to take a statement such as
gradF1(X(t)).X'(t) = 0, which would have been properly defined (how) in
Maple (i.e. the functional relations would be "live") and be able to
determine the d/dt of it (the multivariable chain rule) to get the result ->
transpose(X'(t).delsquareF1(X(t)).X'(t)+gradF1(X(t)).X"(t)=0.
It would be nice to obtain this for F1 introduced as F1 rather than some
specific 2 or 3-D function.
Thanks for your time.
