Rectangular and Polar coordinates:
Questions to guide thinking:
1. How are the values for the Rectangular coordinates chosen? How are the values for the Polar coordinates chosen?
2. Turn off the check box "Show Polar Coordinates". How could you still find out the distance bettwen A and the orgin?
3. Turn off the check box "Show Rectangular Coordinates" and turn back on the check box "Show Polar Coordinates". How could you still find out the x and y coordinates using the degree and radius (Hint: make a right triangle and use trig rules.)
