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
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}]]
Thanks so much for your response, it was a great help. However, I do not understand where the vector function came from on the 1st line of your solution - {x + y, y - z, x^2 + 2 z}, and the Pi/10 as your last entry.
Thanks again. It is apparent that you have an excellent knowledge of both mathematics and the programming language. I certainly appreciate your help.
