 Author Comment/Response Matthias 06/08/13 10:18am Hi, i made a function by interpolating points with "Interpolation[points, InterpolationOrder -> 1] Now i want to compare this function with another and see where they meet. I couldnt manage it with "SOLVE". I sure there is an easy way, but i cant find it. Here is how it looks right now: thanks for your help! points = {{0, 0}, {1, -1}, {2, -1}, {3, -1}, {4, -0.5`}, {5, 0}, {6, -1}, {7, -1}, {8, -1}, {9, -1}, {10, 0}, {11, -1}, {12, -0.75`}, {13, -0.5`}, {14, -0.25`}, {15, 0}, {16, -0.25`}, {17, -0.5`}, {18, -0.75`}, {19, -1}, {20, 0}}; (*Function Polygon*) f = Interpolation[points, InterpolationOrder -> 1]; point1 = {0.5, -0.5}; g [x_] := -1 + x Plot[{f[x], g[x]}, {x, 0, 20}] Solve[f[x] == g[x], x] URL: ,
