4. Graphing Trigonometric Functions

In Exercises 29–44, graph two periods of the given cosecant or secant function.y = 2 sec(x + π)

In Exercises 45–52, graph two periods of each function.y = sec(2x + π/2) − 1

In Exercises 45–52, graph two periods of each function.y = csc|x|

In Exercises 53–54, let f(x) = 2 sec x, g(x) = −2 tan x, and h(x) = 2x − π/2.Graph two periods of y = (f∘h)(x).
