in polys9 there is partial support for this implemented in solve() (only when inequality solver is used), e.g.: In [1]: var('x', real=True) Out[1]: x In [2]: solve(x**2 - 2*x + 1 > 0, x) Out[2]: [(-∞, 1), (1, ∞)] In [3]: solve(x**2 - 2*x + 1 > 0, x, relational=True) Out[3]: x < 1 ∨ 1 < x In [4]: solve([x**2 - 1 >= 0, x**2 - 1 <= 0], x, relational=True) Out[4]: x = 1 ∨ x = -1 > -- > You received this message because you are subscribed to the Google Groups > "sympy" group. > To post to this group, send email to sy...@googlegroups.com. > To unsubscribe from this group, send email to > sympy+unsubscr...@googlegroups.com. > For more options, visit this group at > http://groups.google.com/group/sympy?hl=en. > -- Mateusz
