Hi;
I am trying to create a VectorPlot3D of a vector field that is not actually given. However, I am given a parametric representation of the path, which I should be able to use to create the vector - see attached notebook.
In any event, I am thinking that someone in the community, that has more knowledge than what I have, can help me understand what I am doing incorrectly.
Thanks,
Mitch Sandlin
The vector field is just a sample, I came to that formula following a false trail that it is embarassing to recall. The Pi/10 simpliy means that I divide the interval between 0 and 2Pi into 20 parts.
You can always resort to graphic primitives:
f[x_, y_, z_] := {x + y, y - z, x^2 + 2 z}; r[t_] := {Sin[t], 0, Cos[t]}; Graphics3D[Table[Arrow[Tube[{r[t], r[t] + f @@ r[t]}]], {t, 0, 2 Pi, Pi/10}]]
