Greetings! OK, I've attached my little program below, together with
some tex output changes. It would be nice to not have to toggle phv
and just deal with a variable phase at all stages of the calculation,
but I can't get the simplifications right. Also, would be great if I
could achieve the tex output without overwriting the functions in
lisp.
Advice/suggestions from the experts most welcome.
