[sage-support] Higher order differentiation for multi-dimensional function

I really want to have a generalised differentiation method for functions whose output is a vector. This is really important in practice. For exemple: f(v) = h*v b(v, w) = f(v) * cos(w) + d - sqrt(d**2 - f(v)**2 * sin(w)**2) F(x, y, theta, v, w, a) = (x + b(v,w) * cos(theta), y + b(v,w) *
