Polar Coordinates! (Intro)
[color=#000000]The applet below illustrates how to plot points whose coordinates are written in [b]POLAR FORM[/b]. [br]You can adjust the values of [/color][color=#0000ff][b]r[/b][/color][color=#000000] and [/color][color=#980000][b]theta[/b][/color][color=#000000] by using the sliders or the input boxes. [br](This grapher will only accept [/color][color=#980000][b]theta[/b][/color][color=#000000] values ranging from [/color][color=#980000][b]-2pi to 2pi[/b][/color][color=#000000]). [br][br]Slide the [b]black slider[/b] to illustrate how polar coordinates are plotted. [br][/color][br][color=#000000]Interact with this applet for a few minutes, then answer the questions that follow. [br][/color]
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!

Polar Function Grapher
|
The following applet serves as a polar function grapher. Simply enter the polar function in the upper left hand corner. (You'll need to replace all your "theta" with "t" when entering your function. The green slider below starts from t = 0 and goes to t = 4pi. |
