David: For a start you can try the following: Using ContourPlot ContourPlot[(x - 2)^2 + 2(y - 3)^2 - 6, {x, -1, 5}, {y, -1, 5}, Contours -> {0}, ContourShading -> False, ContourSmoothing -> 5] Or using ImplicitPlot << Graphics`ImplicitPlot` ImplicitPlot[(x - 2)^2 + 2(y - 3)^2 == 6, {x, -1, 5}] ImplicitPlot[x^3y + y^3 == 9, {x, -4, 4}] Hans "David" <davidol at hushmail.com> wrote in message news:anp1hu$r1v$1 at smc.vnet.net... > How can I plot functions like: > > (x-2)^2 + 2(y-3)^2 = 6 > > and > > x^3y + y^3 = 9 > > using Mathematica? > > > >
