2. (a) Draw and parametrize the circle of radius two centered at (1,-1,1) and lying on the plane z+y+z=1. Hint: find two orthogonal unit vectors which are parallel to the plane. (b) Find parametric equations for two circles C₁ and C₂ in space such that C and C₂ have the same radius; C and C₂ intersect at the points P(2,-1,3) and Q(2, 1, 3) and nowhere else.
