Let L1 be the line passingthrough thepoint P1=(?3, ?1, 1) with directionvector ?d1=[1, ?2, ?1]T, andlet L2 be the line passing through thepoint P2=(8, ?3, 1) with directionvector ?d2=[?1, 0, 2]T.
Find the shortest distance d between these two lines, andfind a point Q1 on L1 anda point Q2 on L2 sothat d(Q1,Q2) = d. Use thesquare root symbol '?' where needed to give an exact value for youranswer.
Q1 =
Q2 =
