Free exercises with illustrations and solutions. Soh, cah, toa sin is used when given the opposite and the hypotenuse sinx = opposite/hypothenuse soh cos is used when given the adjacent and the hypotenuse cosx=adjacent/hypothenuse cah tan is used when given the opposite and adjacent [tanx= o.
A common use of mnemonics is to remember facts and relationships in trigonometry.
However, trigonometry is equally applicable to all angles, from 0 to 360°. If two right triangles have equal acute angles, they are similar, so their side lengths are proportional.
