Hi,
is it possible to create a 3d plot of a smooth function f[x,y] (e.g. via
Plot3D[...]) and mark specific contour levels in this plot?
To add some flesh:
f[t_]:= Exp[-t/2];
g[u_,v_,w_]:=BetaRegularized[u, v + 1, w - v];
Plot3D[g[f[x], y,200], {x,0,10}, {y,0,200}]
In this plot (with Mesh->False and increased PlotPoints) I'd like to mark
the contours at 0.5, 0.5+/- 0.3413.
Is this possible?
Thanks for any help/link
Carsten
