Best ResponseYou've already chosen the best response.2SOH, CAH, TOA is a handy way to remember the trig ratios It's pronounced as "soak, a, toea" (that's how I remember it anyway) For SOH S = sine O = opposite H = hypotenuse which means sine(angle) = opposite/hypotenuse For CAH C = cosine A = adjacent H = hypotenuse which means cosine(angle) = adjacent/hypotenuse For TOA T = tangent O = opposite A = adjacent which means tangent(angle) = opposite/adjacent
