I see what you mean. However, my guess is that I won't run into this problem (unless I do something dumb). I'm using Maple to help with the algebraic "crunching" in circuit analysis. In these cases I should always be able to solve for Vo/Vi (the transfer function) with no ambiguity. Thanks for the great help!

I guess that does work, but I was after the more "pretty" solution provided by Acer. ;-) Thanks!

Thank you very much-- that's exactly what I was trying to do. By the way, what would you call that operation (if not isolating a subexpression)? It was very hard trying to search for help topics originally!!
