Here's a little math problem for yall. I need to find out how to get a perpenticular line from a given line in 3D Space. So for example: (2x, 0y, 4z) --- (4x, 0y, 4z)...how would you find the line perpendicular to that one at either of those points? What if the line was diagonal? (2x, 0y, 4z) --- (8x, 2y, 3z)?
