Lesson 11-1: Polar Coordinate Plane


Sorry, the GeoGebra Applet could not be started. Please make sure that Java 1.4.2 (or later) is installed and active in your browser (Click here to install Java now)

Objective:

The student will be able to name and locate points in polar coordinates and convert points between polar and rectangular form.

  1. Drag point P and compare the cartesian and polar forms of the coordinates.
  2. Drag point P until the Polar Coordinates are (6, 60°). What are the Cartesian Coordinates? Drag P to (6, 120°) and (6, 240°) too. Can you think of a formula to calculate x and y from r and theta?
  3. Drag point P until the Cartesian Coordinates are (4, 4). What are the Polar Coordinates? Drag P to (-4, 4) and (-4, -4) too.Can you think of a formula to calculate r and theta from x and y?
