sec t = 1 / cos t csc t = 1 / sin t cot t = 1 / tan t. Periodic Functions: A function if said to be periodic if . for all θ in the domain of f. The smallest number p for which f is periodic is called the . period. of f. Period of trig functions: Even and Odd trig functions: cosine and secant are even.

With this information, what trig function (cos, sin, or tan) will you use to solve for side XY? Write an equation using A to represent your known angle, ZY to represent your known side, and x to represent the unknown side XY. The final step is once you know the length of XY, adding to XY the additional height.
