Question: How do I plot a parametric vector on a parametric surface in Maple?

Hello everyone,

I have a given parametric surface (u,v) -> F(u,v) where F(u,v) is a vector in R^3 and a parametrized vector field (u,v) -> G(u,v) where G(u,v) in R^3. Is it possible to plot the surface together with the vector field so that for some subset {(u_1,v_1),....,(u_n,v_n)} of the parameter set the vector G(u_i,v_i) is plotted at the surface point F(u_i,v_i) for i=1,...,n ?

If it is not directly possible to do this, is there any workaround?

Please Wait...
