Equation of line of shortest distance between two skew lines: direction vector for JEE

Formula

\(\vec d=\vec b_1\times\vec b_2\)

Variables: \(\vec b_1,\vec b_2\) are direction vectors of the two skew lines; \(\vec d\) is direction vector of their common perpendicular.

Conditions: \(\vec b_1\times\vec b_2\neq \vec 0\).

Constructing the line representing the shortest distance between skew lines.
