trig Cheat Sheet Definition of the trig Functions Right triangle definition For this definition we assume that Unit circle definition p For this definition q is any angle. 0 < q < or 0 < q < 90 . 2 y ( x, y ). hypotenuse 1. y q opposite x x q adjacent opposite hypotenuse y 1. sin q = csc q = sin q = =y csc q =. hypotenuse opposite 1 y adjacent hypotenuse x 1. cos q = sec q = cos q = = x sec q =. hypotenuse adjacent 1 x opposite adjacent y x tan q = cot q = tan q = cot q =. adjacent opposite x y Facts and Properties Domain The domain is all the values of q that Period can be plugged into the function. The period of a function is the number, T, such that f (q + T ) = f (q ).
