Hey nrr5094.
You need to find a vector which is perpendicular to both lines (Hint: think about the cross product of the directional vectors of each line)
Urgent! Please help soon! Here's the equation:
Find the distance between the lines:
r1(t) = (1,2,3) + t(0,-1,2)
r2(t) = (0,1,1) + t(1,1,0)
So far all I've been able to figure out is conversions to unit vector i, j, and k:
r1(t) = 0i + 1 -j +2 +2k +3 = -j + 2k + 6
r2(t) = i + j + 1
But here I hit a block....please help!
