Talk:Orthogonal transformation
Appearance
The text of this article was an almost exact copy of the Mathworld article. As of today, the difference consisted of the leading words "In linear algebra,", a misspelling (or a grammatical error), and a single sentence deleted.
I can't believe this does not violate copyright.
I have written a new article with similar contents. The sources I have used are mostly other related Wikipedia articles, as well as the Mathworld article for the exact definition. Cacadril (talk) 00:44, 27 May 2012 (UTC)
