<S>ine is <O>pposite the <H>ypotenuse
<C>osine is <A>djacent to the <H>ypotenuse
<T>angent is <O>pposite over <A>djacent.
Sometimes written as "soh cah toa."
Sine = Opposite/Hypotenuse
Cosine = Adjacent/Hypotenuse
Tangent = Opposite/Adjacent
Problem is, who can remeber how to spell this supposed Indian Princess name? Much better mnemonic is Sally Can Tell (sine/cosine/tangent in the vertical column) Oscar/Has, A/Hard, On/Always (opposite/hypotenuse, adjacent/hypotenuse/, opposite/adjacent, also vertically).
Mnemonic device for SOHCAHTOA, referring to the trigonometric method of finding the sine, cosine, and tangent of a right triangle.
Gareth And Callum: SOHCAHTOA!!!!
Mr E: grrr Gareth move !!! blah bla blah scraping a C blah bla blah
