An interactive tutorial on how to plot points given by their polar coordinates. This tutorial also help in gaining a deeper understanding of polar coordinates and may be used with another tutorial on Graphing Polar Equations. Free polar graph paper is available.
Interactive Tutorial Using Java Applet
1  Click on the button above "click here to start" to start the applet and maximize the window obtained.
2  To plot a point given by its polar coordinates, enter the radial coordinate r and the angular coordinate t (in degrees) and press "plot". To delete all points plotted press "delete all".
3  Plot points with radial coordinate r constant. Examples: (2 , 45) , (2 , 120) , (2 , 720) , (2 , 900). Change r and start again. What do you notice?
4  Plot points with angular coordinate t constant. Examples: (3 , 45) , (4 , 45) , (2 , 45) , (5 , 45). Change t and start again. What do you notice?
5  Plot the pair of points: (3 , 120) and (3 , 120). What do you notice?
6  Plot the pair of points: (4 , 30) and (4 , 30). What do you notice?
7  Repeat plotting pairs of the form (r , t) and (r , t) and explain the positions of the points.
8  Plot the points (3 , 45) , (3 , 405) , (3 , 765) , (3 , 315). Explain the position of these points.
