 Author Comment/Response Asatur 12/13/12 2:16pm Hi everybody. I have a system of equality type constraints on different functions with the same variable, but neither FindRoot nor Solve could not give the answer. I was advised to find the solution by plotting graphs of the functions and find the points of their intersections. I can find the way to do that for two functions, but can not for many. Here is the algorithm f[x_] := Cos[2*x + 1] - 1 g[x_] := Cos[3*x - 1] - 1 solution = Solve[f[x] == g[x], x][[All, 1, 2]]; Plot[{Tooltip[f[x], f[x]], Tooltip[g[x], g[x]]}, {x, -Pi, Pi}, Epilog -> {Red, PointSize[0.01], Tooltip[Point[{#, f[#]}], FullSimplify[{#, f[#]}]] & /@ solution}, ImageSize -> 600, PlotStyle -> Thick] How can I do the same for 3 or 4 functions?
