Graphing tangents to polar graphs

Hey guys,

How do I make my TI-83+ graph the line tangent to a polar graph given some theta? Is my calculator capable of doing this, or must I find the equation analytically?

Thanks.

1. Switch the calculator into polar mode.

2. Draw the graph.

3. Choose DRAW (=2ND PRGM) 5: Tangent(

4. The cursor is placed on the graph. Choose a point by the cursor or enter a value of .

5. Press ENTER
