Given a point E or any object with a polar coordinate of
∠ ° , meaning the radius is 4 and the angle is 120 degree. Counter clockwise rotation of the angle (CCW rotation)
is the default rotation.
DEFAULT ROTATION IS COUNTER CLOCKWISE FROM POSITIVE X-AXIS BECAUSE IT CORRESPONDS TO CARTESIAN COORDINATE
Compute its equivalent rectangular coordinate or cartesian coordinate:
