    distance between two skew lines.

    Find the distance between two skew lines:
    L1: x = 2s, y = 2s - 1, z = s + 1, and
    L2: x = t, y = 2t - 2, z = 3.

    If P+tD~\&~Q+sE are two skew lines, the the distance between them is \frac{{\left| {\overrightarrow {PQ}  \cdot \left( {D \times E} \right)} \right|}}{{\left\| {\left( {D \times E} \right)} \right\|}}

    Find the direction vector of each line. Those are D~\&~E.

    Find a point on each line. Those are P~\&~Q

    Then use the formula.
