When do I use Sin, Cos and Tan?

Just remember SOH,CAH,TOA. It sounds like Sock-A-Toe-Ah. Quite strange but extremely effective. SOH means Sin=Opposite/Hypotenuse Cos=Adjacent/Hypotenuse Tan=Opposite/Adjacent The three letters in each abbreviation represent the first letter in each word of the formulae.
