Conversion between Cartesian and Polar Coordinates by lucienyoung

This example demonstrates the conversion between Cartesian and polar coordinates using the instance ρ=cosθ. The core mathematical concepts involved include the polar coordinate transformation formula and the Cartesian coordinate system. The construction points include using the GeoGebra CurveCartesian command to draw the Cartesian coordinate system, using the ρθ object to draw the polar coordinate system, and using the text1-7 objects to add labels and explanations. This example is suitable for middle school and high school mathematics education, particularly for teaching analytic geometry and calculus.
