It appears the Solve and O[x] don't mix. Consider the following. Mathematica 2.0 for NeXT Copyright 1988-91 Wolfram Research, Inc. In[1]:= Solve[x+z==1,x] Out[1]= {{x -> 1 - z}} In[2]:= Solve[x+z==1+O[z],x] Out[2]= {{x -> 1}} (* I would prefer x -> 1 + O[z] *) In[3]:= Solve[x+z==1+O[z]^2,x] Out[3]= {} (* What is wrong with x -> 1 + z + O[z]^2 ??? *) -- ..STeve ------------------------------------ Insert pithy maxim here... steve at tweedledee.ucsb.edu (NeXT mail)
