A common use of mnemonics is to remember facts and relationships in trigonometry. For example, the sine, cosine, and tangent ratios in a right triangle can be remembered by representing them and their corresponding sides as strings of letters. For instance, a mnemonic is SOH-CAH-TOA: [34]
Unlike the soa-cah-toa nemonic it gives all six common functions. But I like to teach only the 1st three, OH, AH, Oh-Ah (simple enough), or even only the first two, OH AH -- and have them (students) memorize only Sin, Cos, and Tan -- then have them learn and understand that tan= sin/cos and the last three are inverses of the 1st three.
