Hi all, I'm teaching vector calculus, and I would like to show the meaning of the curl to my students. So here is what I want to do:
1. Plot a 2d-vector field F = (P,Q) (I know ho to do this) 2. Compute the k-component of this field (o.k) 3. Plot part of the 3d-vector field curl(P,Q,0), more precisely, only the vectors that have starting points in the z=0 plane. It all need to be in a 3d-plot, so I would like to know if one can embed the plot of 2d field in a 3d plot. Of course I could plot the vectors "manually", tnat is computing them point by point, but this seems highly inelegant and cumbersome. Any idea someone? -- You received this message because you are subscribed to the Google Groups "sage-support" group.
