Talk:Sum of Squares of Sine and Cosine
From ProofWiki
Any problem with including the geometric proof from Trigonometric Identities? --Cynic (talk) 01:17, 29 January 2009 (UTC)
Not at all. We need to start to be careful about which of the threads (Geometric or Algebraic) one is proving from, because otherwise the proofs will be circular. Might need to rethink how we present these proofs. --Matt Westwood 06:29, 29 January 2009 (UTC)
