How To Remember Sine, Cosine, Tangent The Trig Formulas, or Trigonometric Formulas, for finding the Sine, Cosine, and Tangent of an angle in a triangle, have given students a lot of trouble over the years. Here are a few ways that people have devised to help remember them. Choose your favorite! First of all, the formulas themselves: Sine = Opposite/Hypotenuse Cosine = Adjacent/Hypotenuse Tangent = Opposite/Adjacent Easy, aren't they? (not) Probably the most common way people remember them is by thinking of the name of the fictitious volcano, SOHCAHTOA. This is OK but a bit boring, and not always secure. I have seen it spelt as Soccertoa, which is not a whole lot of use. A bit more interesting is: Tommy On A Ship Of His Caught A Herring or this one: The Old Army Colonel And His Son On Holiday or maybe this one: Sex On Holiday Comes After Having Tankards Of Ale Which one is YOUR favourite?
