Trig Cheat Sheet. Definition of the Trig Functions. Right triangle definition. For this definition we assume that. < q. p. 0 < or 0 ° < q < 90 ° . 2. hypotenuse opposite. q. adjacent. Unit circle definition. For this definition q is any angle. y. ( x , y ) q x. opposite. sin q = hypotenuse. q = adjacent. cos hypotenuse. q opposite. tan = adjacent.
Trig identity reference. Google Classroom. Look up AND understand all your favorite trig identities. Reciprocal and quotient identities. sec ( θ) = 1 cos ( θ) Explain. 1. csc ( θ) = 1 sin ( θ) Explain. 1. cot ( θ) = 1 tan ( θ) Explain. 1. tan ( θ) = sin ( θ) cos ( θ) Explain. cot ( θ) = cos ( θ) sin ( θ) Explain. Pythagorean identities.
The period of a function is the number, T , such that f ( + T ) = f ( ). So, if ! is a fixed number and is any angle we have the following periods. sin (! ) ! 2 T = ! cos (! ) ! 2 T = ! tan (!
