In the general equation of a curve that passes through the origin,

u1 ≡ a1x + b1y = 0 is the equation to the tangent at the origin; for, y q g when x and y are very small, we may neglect all the terms in comparison with those involving the first powers of x and y. If neither a1 nor b1 vanishes, we may, without loss of generality, write the equation in the form
