Question
Let D1 and D2 be two lines of R3.
(a) Calculate the distance between lines D1 and D2; explain your calculations by giving the meaning of the different elements in the formula used.
(b) Give the coordinates of the point P ∈ D2 closest to the point X(1,3,0).
(c) What is the distance between D1 and D3: (x, y, z) = (−6,7,−3) +t(2,−6,8)? Give the meaning of the different elements appearing in the formula used.

D₁ : x + 2 = 4y
= 4y = 2+³ D₂ : (x, y, z) = (3, 5, —2) + t (−1, 1, −1)
