If is one end of a diameter of the sphere , then the coordinates of the other end of the diameter are
Finding coordinates of other end of the diameter:
The equation of sphere is where , , and are constants.
The center of sphere is .
The given equation of sphere is . So the center of sphere is .
The coordinates of one end of diameter is .
Let the coordinates of other end of diameter be .
Hence, the coordinates of other end of the diameter are .
