    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 \theta.

    5. Press ENTER
