Another way of representing trigonometric functions is to use polar coordinates. In this system the coordinates (r, θ) represent a radius and an angle of rotation. In the first diagram, the radius of the terminal arm is and the angle is Use the table of values you created in Try This 2 to plot r = sin θ on a polar grid.
Use the following polar grid to create your graph of r = sin θ.
Use Polar Functions Explorer to check your graph.
