Only way I can see to fix this is to try and substitute -1 or 1 for every sign(var) instance and see if it belongs to [-oo, oo] in every case. But what if it is -oo/oo sometimes and sometimes not. What output should we give then? Would a simple "Output depends on sign" suffice? -- You received this message because you are subscribed to the Google Groups "sympy" group.
