- What is this video about?
This video explains why sine and cosine graph do not have an ASYMPTOTE. It also includes some other trigonometric functions that have asymptotes in their graphs. By using the Unit Circle ratio, asymptote appears where the value of the denominator becomes undefined.
- What does the viewer need to pay special attention to in order to understand the concept?
For this type of question, the readers might want to pay attention to the unit circle ratio. They might see why the cosine and sine trigs actually relate to other trigonometric function.
A good source for sine and cosine graph: http://www.purplemath.com/modules/triggrph.htm
It shows how to get the value from the unit circle and then put into the graph. It only has the explanation for sine and cosine graphs.

This is a Unit Circle. It will be helpful for you to review a little bit about the point value of each quadrant and trigonometric functions.
