Multiple Choice
What is the main difference between rectangular and polar coordinates?
Rectangular coordinates use angles and distances from the origin.
Polar coordinates use x and y values.
Rectangular coordinates use x and y values, while polar coordinates use angles and distances from the origin.
Polar coordinates are only used in physics.
