Let S1*(S2*) be the polar cone of the set S1(S2) (http://en.wikipedia.org/wiki/Dual_cone_and_polar_cone).(adsbygoogle = window.adsbygoogle || []).push({});

How can I show that if S1 is contained in S2 then S2* is contained in S1*.

It looks obvious (especially if we think in R^2), but I do not find a way to prove it.
