I think that you are mistaking the memory tool for something else or a math book is trying to make math cute by calling them 'socatoa joe' and 'mr. pi' and such
anyway, SOH, CAH, TOA is the way to remember Sine=oposite/hypotonuse Cosine=adjacent/hypotonuse Tangent=oposite/adjacent
(oposite side=side oposite the angle adjacent is the side touching the angle that is not they hypotonuse and of course the hypotonuse is the longest side aka, side oposite right angle)
