## Homework Statement

I want to plot the following function into Maple14. [tex]\vec{v}=frac{1}{\vec{r^{2}}} \hat{r}[/tex]

**In case the latex is screwed this says v=r^(-2) *r-hat

## The Attempt at a Solution

My code for Maple is the following, but it doesn't seem to work.restart; with(LinearAlgebra); with(VectorCalculus); with(plots);

SetCoordinates('cartesian'[x, y, z]);

vec := Vectorfield(<1/x^2, 1/y^2, 1/z^2>)

fieldplot3d(vec, x = -1 .. 1, y = -1 .. 1, z = -1 .. 1, axes = normal)

For which I get the following error (Maple website has no information on this error);Error, (in plots/fieldplot3d) invalid 1st argument (the function) Vectorfield(Vector(2, {(1) = 1/x^2, (2) = 1/y^2}, attributes = [coords = cartesian[x, y]]))

Basically I need someone to explain why Maple will not plot this vectorfield.
