Polar Coordinates! (Intro)

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!
