Look at this example: In[1]:= Reduce[x foo[x] == 0] Solve::tdep: The equations appear to involve transcendental functions of the variables in an essentially non-algebraic way. Out[1]= Reduce[x foo[x] == 0] In[2]:= Reduce[id[x] foo[x] == 0] Out[2]= id[x] != 0 && foo[x] == 0 || id[x] == 0 (x, foo[_], and id[_] are undefined). What I want is the behavior of the second expression without having to replace x with something like id[x] everywhere it appears alone. (Note: this is a stripped down example. My real equation has dozens of terms.) Can anybody help me? Thanks. (BTW, with MMA on the NeXT, how do you copy part of a notebook and paste it in a mail message, without losing the In[_] and Out[_] labels? I'm getting tired of adding them by hand.) -- Alex Dommasch, Programmer |-- Field-Flow Fractionation Research Center |- Department of Chemistry, University of Utah V Salt Lake City, Utah 84112 |->|..
