  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:
  
  One way to remember the letters is to sound them out phonetically (i.e. / ˌ s oʊ k ə ˈ t oʊ ə / SOH -kə- TOH -ə, similar to Krakatoa). Another method is to expand the letters into a sentence, such as " S ome O ld H ippie C aught A nother H ippie T rippin' O n A cid".
