I forget the slightly filthy acronym that goes with it, but it decodes as: SOH - Sine is Opposite over Hypoteneuse CAH - Cosine is Adjacent over Hypoteneuse TOA - Tangent is Opposite over Adjacent

E electro eto Joined Oct 5, 2006 4 Oct 10, 2006 #3 well i always use OHSAHCOAT. the pronounciation alone could not be any easier. OH=S i.e OPPOSITE/HYPOTHENUS =SINE AH=C i.e ADJACENT/ HYPOTHENUS =COSINE OA=T i,e OPPOSITE/ADJACENT = TANGENT well thats the easiest way i learn it. work form me so hopefully it should work fro u too.
