1. Observe the Rectangular coordinates. Move point A and note that the coordinates change for both the Rectangular and Polar. 2. click the checkbox for Show Polar Coordinates. 3. Recall the pythagorean theorem or the distance formula. What relationship can you see between the Rectangular coordinates versus Polar coordinates based on the pythagorean theorem or distance formula? 4. Recall the trigonometry mnemonic SOH-CAH-TOA. How can you relate this to the difference between the Rectangular and Polar coordinates?
