Question
Let S₁ and S₂ be the spheres with equations
x² + y² + z² - 2x +2y-2z+2
x² + y² + z² - 4x - 2y + 2z - 10
= 0 and
= 0,
respectively.
a) Find the centres and radii of S₁ and S₂.
b) Show¹ that the two spheres intersect in one single point and S₁ is
contained in S₂.
c) Do the two spheres intersect on the plane P = {(x, y, z) = R³ :
x + 2y – 2z = 0}? Justify your answer.
