U3.08

Polar and non-Cartesian scales

Cards in this group · 5

  1. U3.08.1Polar coordinates map one variable to angle, the other to radius
  2. U3.08.2Equal radius increments give unequal areas; outer rings are systematically enlarged
  3. U3.08.3Polar coordinates suit inherently periodic variables
  4. U3.08.4Radar-chart axis order changes the polygon's shape and area
  5. U3.08.5Magnitude comparison under polar coordinates is harder than in Cartesian
