Definition talk:Inverse Sine/Arcsine

I've been taught that, while $$sin^{-1}$$ is misleading (and in fact does not exist), $$Sin^{-1}$$ (capital S) is defined to be the same as $$arcsin$$. Has anyone else learned this, or is it just my teachers being weird? --Cynic (talk) 18:21, 31 January 2009 (UTC)
