Is there an easy method on how to remember the trig. ratios on a right angled triangle...tan, cos, sin..? I always find myself referring to my notes.
From my class in conventional machining which I took at the local community college SOH CAH TOA (pronounced SOO-KAA-TOW-AH). 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
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.
A favourite phrase of mine for remembering SOHCAHTOA was: Smiles Of Happiness Come After Having Tankards Of Ale You may also begin enjoying trigonometry! Dave
