Theorem Conversion from Polar Coordinates to Rectangular Coordinates
Steps for Converting from Rectangular to Polar Coordinates
STEP 1: Always plot the point (x, y) first. STEP 2: STEP 3: To find r, compute the distance from the origin to (x, y). To find first find the quadrant it belongs that the point lies in.
Find polar coordinates of a point whose rectangular coordinates are (-3, 4).
