Interact with this resource for a minute or two. Then answer the questions that follow.

## 1.

Why does the **purple arrow** represent the value of the **tangent **of the angle? How do you know this?

## 2.

If we kept going around the circle (past ), what would the graph look like (on the right) to the right of the vertical line ?

## 3.

Why are there vertical asymptotes at and ? Are there other asymptotes for the function ? If so, how would you describe where they are?
