Equivalent equation of common perpendicular through the other foot point for JEE

Formula

\(\vec r=\vec r_2+t(\vec b_1\times\vec b_2)\)

Variables: \(\vec r_2\) is the foot of the common perpendicular on the second line.

Conditions: \(\vec r_2\) corresponds to the same common perpendicular.

Alternative form of the shortest-distance line.
