I have two polynomials $p(x)$ and $q(x)$ and I want to know if there are roots of the equation $\frac{p'}{p} = \frac{q'}{q}$ in the domain $(a,\infinity)$ - where $a = max \{ roots(p),roots(q) \}$This is the same as asking for the roots of the polynomial, $p'q - pq' = 0$ in the same domain. - Can something in Sage help?
Just compute all roots and filter out the ones which satisfy your condition. -- You received this message because you are subscribed to the Google Groups "sage-support" group.
