*Problem:*

Graph the curve represented by the following equation in polar coordinates:

*Visualization:*

Using Derive:

- Prepare the program for graphics.
- If the first menu item is
*Algebra* then press .
- Press for
*Author*.
- Enter the function
3sin(9 )
- Press to get the plot window.
*Now we need to prepare Derive to graph in polar coordinates.*

- Press to enter the options menu.
- Now press to enter the state menu.
- Finally, press and then
to tell Derive to graph using continuous polar coordinates.
**Note: Derive will continue to graph in polar coordinates for the remainder
of the session or until the state is chaged back to rectangular.**

- Now press and then to see the graph.
