How do you prove the following equation?

My impression is that it just can't be right because the right-hand-side does not depend on the constants  . This is an important problem because the identity is used in the proof of Carathéodory's criterion in this article. Zatrp (talk) 10:19, 13 May 2014 (UTC)Reply
