Trigonometry and Polar Coordinates Construct graphs of polar functions. The graph of the function r = f ( ) in polar coordinates consists of input-output pairs of values where the input values are angle measures and the output values are radii. 3.14.A.2 The domain of the polar function r = f ( ), given graphically, can be restricted to a desired portion of the function by selecting endpoints corresponding to the desired angle and radius. 3.14.A.3 When graphing polar functions in the form of r = f ( ), changes in input values correspond to changes in angle measure from the positive x-axis, and changes in output values correspond to changes in distance from the origin.
