I am stuck on this Self-test 1.6 in molecular quantum mechanics by atkins and friedman.(adsbygoogle = window.adsbygoogle || []).push({});

Probably making use of the completeness relation the question is the following: Show that if <Ωf>*=-Ωf*, then <Ω>=0 for any real function f.

Anyone got a clue?
