Polar graph analysis example
Polar graph analysis:
- graph (online/calculator ok)
- find max $|r|$ value and all $\theta$ where it occurs
- symmetry tests
- x-axis, y-axis, origin (rotation by $\pi$)
- look at graph and verify any symmetries you see (this example has all three, but you only need to check the ones you see on the graph)
