merge with trigonometric identity[edit]

primarily to MarkSweep: This makes perfect sense to me, and seeing the sparse edit history I don't think anyone is going to take too much offence at anyone doing this... In fact, would you mind if I did? (me being a beginner and all, and not that practiced in the technical wiki arts, of which wikipedia seems to have a disproportionate amount!)

Go right ahead. Be bold! You may want to check to what extent some of the identities here are subsumed by what's already present over at trigonometric identity. --MarkSweep 21:12, 27 Apr 2005 (UTC)
