Symmetry: In graphing polar functions, symmetry refers to patterns or characteristics that are repeated across the x-axis, y-axis, or origin in the polar coordinate system.
Periodicity: Periodicity in graphing polar functions refers to the repetition of patterns as you rotate around the origin. It is similar to how certain shapes or designs repeat after every full rotation on a spinning wheel.
Polar Coordinates: Polar coordinates are pairs of numbers (r, θ) that represent points in a two-dimensional plane using an angle (θ) and distance (r) from the origin. They are used in graphing polar functions to locate points on the coordinate system.
