I think it's very unlikely that they are wrong, but there might be some printing error. I notice that a superscript zero has been used instead of the degree sign, which is not in itself important but could be significant. This sort of equation and a derivation tends to appear only in advanced textbooks that are only found in libraries. -- OOO - Own Opinions Only.
