‡ For example, a curve branch in three dimensions in its simplest form is given by equations of the type x = tρ, y = t σP, z = t τQ (P, Q being power series in t, not vanishing at t = 0). But any plane projection of this branch (except from the points at infinity on the axes of y or z) has the general form (2) above.
