Interact with the applet below for a few minutes. Then answer the questions that follow.

## LARGE POINTS are MOVEABLE. Be sure to slide the slider (lower right) slowly. As you do, pay careful attention to what you see here.

## 1.

Just by merely observing the dynamics of this applet, what would the **tangent of 45 degrees **be?

## 2.

What would the **cotangent of 45 degrees** be?

## 3.

Do the values of **either of these ratios** depend upon **the length of the circle's radius**? Explain why or why not.
