Is there a way to restrict a function of two variables to points on a curve in the xy-plane?
For example, f(x,y) = x^2-3y^2 restricted to x^2+y^2=1.
depende de la complejidad de la curva y de sus parametrizaciones
en tu ejemplo a = Curve(cos(t), sin(t), f(cos(t), sin(t)), t, 0, 2π)
pero si la curva no es parametrizable yo uso locus()
f(x,y) = (x^2-3y^2)*(x^2+y^2<1)
Thanks for the input Michael. This wasn't exactly what I was looking for, but I can see this being useful in the future.
Thanks mathmagic. This definitely works, but I was wondering if there was a nonparametric method for more difficult curves in the xy-plane. If not, no worries, as I mostly need to create ellipses in the xy-plane. Thanks again.
