Distance Between Intersecting Lines, Parallel Lines,...
https://3speak.tv/watch?v=mes/anraunpm In this video I discuss how to determine the distance between two lines for each of the 3 possible cases: intersecting lines, parallel lines, and skew lines. If two lines intersect, their distance is zero, and we can equate their parametric equations and solve for each parameter. If there is no solution, then the lines do not intersect. If two lines are parallel, then the cross product of their direction vectors is zero. We can solve for the distance between
