u = c (cos θ, sin θ, 0) .

Part (ii) gives the first-order changes

δ u_{x} = - V sin^{2} θ, δ u_{y} = V sin θ cos θ .

For a vector of fixed leading-order magnitude

c

, its small change of angle is

δ θ = \frac{u _{x} δ u _{y} - u _{y} δ u _{x}}{c ^{2}} .

Substitution yields the relativistic aberration formula

θ^{'} - θ = \frac{V}{c} sin θ

to leading order.
