Quick-Start Trigonometric Function Graph Using Polar Coordinates The following example shows how you can graph a trigonometric function using polar coordinates. Note that the procedure consists of four parts: specifying the graph type, specifying the unit of angular measurement, specifying the range parameters for the graph, and actually drawing the graph. Example: To draw the graph for: r = 2sin 30. To specify the graph type Use the following procedure to specify polar coordinates for the I SET UP graph: (SHIFT, (MENU F2 (POL) . To specify the unit of angular measurement Continuing from the above, use the following procedure to specify radians as the angle unit: c (--) (Rad) EXIT To specify the range parameters (al 1.
