${L_1}:\bar r = \hat i + \hat j + \lambda \left( {\hat i + \hat j - \hat k} \right)$
${L_2}:\bar r = \hat j + \hat k + \mu \left( {\hat j + 2\hat k - \hat i} \right)$ equal to
$\mathrm{L}_{1}: \overline{\mathrm{r}}=\overline{\mathrm{a}}+\lambda \overline{\mathrm{b}}$
$\mathrm{L}_{2}: \overline{\mathrm{r}}=\overline{\mathrm{c}}+\mathrm{m} \overline{\mathrm{d}}$ is
$D = \frac{{\left| {(\bar a - \bar c) \cdot \left| {\bar b \times \bar d} \right|} \right|}}{{\left| {\bar b \times \bar d} \right|}} = \frac{1}{{\sqrt {14} }}$
