The applet below illustrates how to plot points whose coordinates are written in

**POLAR FORM**. You can adjust the values of**r**and**theta**by using the sliders or the input boxes. (This grapher will only accept**theta**values ranging from**-2pi to 2pi**). Slide the**black slider**to illustrate how polar coordinates are plotted. Interact with this applet for a few minutes, then answer the questions that follow.Plot the following points using the calculator above: (3, pi/2) and (-3, 3pi/2). What do you notice?

Can you come up with a different set of polar coordinates for the location given in the first question? If so, list it/them!
