QUESTION #13 Lines in Space
Let L_1:vecr = (hati -hatj +2hatk) + lambda (hati -hatj +2hatk),lambda in mathbbR L_2:vecr = (hatj -hatk) + mu (3hati +hatj +phatk),mu in mathbbR and L_3:vecr = delta (ell hati + mhatj + nhatk) delta in mathbbR Be three lines such that L_1 is perpendicular to L_2 and L_3 is perpendicular to both L_1 and L_2 . Then the point which lies on L_3 is

QUESTION #22 Lines in Space
Let a line passing through the point (-1, 2, 3) intersect the lines L_1: fracx - 13 = fracy - 22 = fracz + 1-2 at M(alpha, beta, gamma) and L_2: fracx + 2-3 = fracy - 2-2 = fracz - 14 at N(a, b, c). Then the value of frac(alpha + beta + gamma)^2(a + b + c)^2 equals
