Unit 3 - Objective 4 - Graphs of y = tan x, y = cot x, y = sec x, and y = csc x
Quick Review

Example 1

The graph for y = tan x
period = pi
asymptotes ... ...

The graph approaches the vertical asymptote but never touches it.


Example 2

The graph for y = cot x
period = pi
asymptotes ... ...



Example 3

The graph for y = sec x
period = 2pi
asymptotes ... ...



Example 4

The graph for y = csc x
period = 2pi
asymptotes ... ...
