What is the major difference between Mathematica version 2.03 and version 2.1? Both versions are installed on various locations on campus, but I can't see any major difference even though their sizes are 3.4 Mb and 4.2 Mb respectively (on the Mac version). What's the beef? While I have your attention, I wonder if you know an easy way to turn the solutions of a Solve from a list of replacement rules to simply elements of a list. Suppose Solve[x==f[x],{x}]={{x->a},{x->b},{x->c}}, I want the list {a,b,c} instead. I have come up with a cumbersome way of doing this which is solns=Table[x/.Flatten[solnlist=Solve[x==f[x],{x}]][[i]], {i,Length[solnlist]}] but I know there must be a better way. Thanks Leon
