Step 1: Understand how polar equations work.
Coordinates in polar equations are of the form (r,θ), where r represents radius and θ represents angle.
This means you rotate θ radians around and go out r units. -
Step 2: Make a table with values of the angle and radius.
Take any random values of θ (around ten values would suffice) and calculate r against each of them using the relationship given between r and θ.
This will help you plot them out on a graph easier, because you can just refer to a table instead of having to come up with coordinates in your head. , The LifeGuide Hub How to Plot Polar Coordinates will be helpful. , -
Step 3: Plot the various (r

Step 4: θ) points as found in the table.

Step 5: Join the plotted points with a smooth curve and you're done!
