I've began learning some Implicit Functions but graphing them seems to be a problem. I'm using MathGV for graphing. Should I choose 2D or 3D graphs? It's not graphing with 2D, and solving for x or y would be an even bigger problem. For instance, 3(x^2+y^2)^2 = 100xy will graph in 3D but is this really a 3D function? Thanks.
