Basic Identities tan (x) = sin (x) cos (x) tan (x) = 1 cot (x) cot (x) = 1 tan (x) cot (x) = cos (x) sin (x) sec (x) = 1 cos (x) csc (x) = 1 sin (x)

For this definition q is any angle. The domain is all the values of q that can be plugged into the function. The range is all possible values to get out of the function. The period of a function is the number, T, …
