Hello, Here is a short Notebook that works pretty well : gr = Plot3D[x^2 + y^2, {x, -2, 2}, {y, -2, 2}, Mesh -> None, BoxRatios -> Automatic]; sol[p_, g_, y0_, vx0_] := NDSolve[{- x''[t] + (- g - (2 x'[t]^2 + 2 y'[t]^2 + 2 x[t] x''[t] + 2 y[t] y''[t])) 2 p x[t] == 0, - y''[t] + (- g - (2 x'[t]^2 + 2 y'[t]^2 + 2 x[t] x''[t] + 2 y[t] y''[t])) 2 p y[t] == 0, z[t] == p (x[t]^2 + y[t]^2), x[0] == 0, x'[0] == -vx0, y[0] == y0, y'[0] == 0}, {x, y, z}, {t, 0, 100}]; a0 = ParametricPlot3D[ Evaluate[{x[t], y[t], z[t]} /. sol[1, 10, 1.5, 1]], {t, 0, 10}, PlotStyle -> Thick]; Show[a0, gr] However, 1) saving the Notebook as a pdf file alters the a0-display in the final output 2) saving the Notebook as a xml file alters some printings like = = (Equal) Suggestions ? Thanks in advance, A. Hautot
