Your best bet is to use simplify_full() instead of simplify: sage: (v-w).simplify_full().is_zero() True That's not guaranteed to work either though. Symbolic equality may not be decidable. When you ask for e.g. `bool(x == y)`, there are three possibilities: * Sage can show that `x` is equal to `y`. It returns True. * Sage can prove that `x` is not equal to `y`. It returns False. * Sage can't tell either way. It returns False. You don't have a good way to distinguish between the last two cases, and the same thing happens with `(v-w).is_zero()`. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
