For just one example, read this story, or just do a search for "texas history textbook controversy." You'll get way over a million results (!).

Or just grab a high school math book that's aligned to state standards and see for yourself. Why prove the law of cosines when you can just write it out in boldface text and announce that it's true? That way, no one has to worry!
