Re: A motion profile problem or Mathcad sucks. Will some other CAS


Actually, I was going to test Robert H Lewis's
solution next.
His solution is the only one that doesn't require
finding roots.
The problem is that I am not familiar with Fermat and
Rober H Lewis
didn't
post the script like you did. Also, I liked the idea
of solving for
the
acceleratons first and then substituting. If Fermat
can calculate any
of the accelerations without finding roots then I may
have a answer.

It is quite easy to find resultants for a1 or a5. If you want to pursue this, you will find my email address on my web site.
