@Rong Ah ok that makes sense now.  So IsEmpty( sys, R) checks whether there are real solutions and IsEmpty( cs, R ) checks whether there are complex solutions.  So my system has a complex solution but no real solutions.  I need to try to find a similar command to IsEmpty( sys, R ) that would work in Maple 15.  I'll post it here if I find one.  Thank you!
