part(fundef(f1),2) gives back x - 2 * sqrt (x), which can be used to
substitute back into the
original expression. It seems that the commercial macsyma does this.
BTW, I plan to be driving between Denver and Boston sometime in the next
2 months,
and would be interested in meeting with list members who live between
those cities.
