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).
