Hi ! I want to solve an implicit equation in Mathematica: The dependence of x and y is given with: z=f[x,y] and I want to solve x=g[y,z] with z=z0. but I can't find the explicit function g. The only possibility I found in the mathematica Book, was to use the ContourPlot. But I need the values too, not only the plot. I experienced with the following solution: X = NSolve[ f[x,y] == z0, x] and for more than one value: X = Table[ NSolve[ f[x,y] == z0, x], {x, xmin, xmax}] I'm a beginner in Mathematica, so I'm not shure, if there is a better and faster possibility.
