# Example 1

Plot the points

*A*= (3, 15°) and*B*= (–3, 1275°) on the polar coordinate system.1. Identify the grid circle that corresponds to the radial coordinate of point A.
2. Identify the grid line that corresponds to the angular coordinate of point A.
3. Mark the intersection of the grid circle and the grid line as point A.
4. Identify the grid circle that corresponds to the radial coordinate of point B.
5. Identify the grid line that corresponds to the angular coordinate of point B.
6. Mark the intersection of the grid circle and the grid line as point A.
