I'm using version 6.0.2.0, so the enourmous capabilities and conveniences of the "Manipulate" function is available to me, and hopefully you. But if not, here are two versions of viewing the results: (1) Plot3D[x^2+y^2, {x,-100,100},{y,-100,100}] (2) Manipulate[Plot3D[a x^2+b y^2, {x,-100,100},{y,-100,100}], {{a,0,"a = -100 to 100"},-100,100}, {{b,0,"b = -100 to 100"},-100,100}] Benjamin Tubb On Mar 15, 3:11=A0am, "Dr. Johannes Zellner" <johannes.zell... at gmail.com> wrote: > Hi, > > How do I make mathematica to display results with all known > relations / variables? > E.g. if a result is > =A0 =A0x^2+y^2 > and before I'd defined > =A0 =A0r = x^2+y^2 > I'd like mathematica to display the result rather as "r". > > And: I'd like mathematica to do this for each relation defined before > w/o specifying every possible replacement. > > Any help much appreciated.
