In this lesson you will learn how to graph the tangent and cotangent functions.

Directions:

1. You will need to read through the web links to the right.
2. Watch the video and pay attention to the key ideas listed.
3. Click on Quizzes to take a quiz over this lesson.

Resources (focus on placement of the asymptotes and how this changes changes the shape of the graphs compared to the other trig function graphs)

Lesson Video

• Notice where the tangent is undefined
  
  
• The midline changes point of inflection
  
  
• Shape is much like the cubic function
