Focus E: Graphing Points on Polar Paper

Alternative approach #1:

• On the polar axis, move to the circle with r = 3.
• Rotate counterclockwise 150° from the polar axis and plot a point D₁.
• Reflect this point across the pole (since r is negative) and plot D on this circle.

Alternative approach #2:

• Move to the circle with r = 3.
• Rotate counterclockwise (150° + 180°) from the polar axis and plot the point D.
