Vector Algebra

$\overline{\mathrm{a}} \times \overline{\mathrm{b}}=\overline{\mathrm{b}} \times \overline{\mathrm{c}}$

$\overline{\mathrm{a}} \cdot \overline{\mathrm{b}}=\overline{\mathrm{b}} \cdot \overline{\mathrm{c}}$

$\bar{a} \cdot \bar{c}=|\bar{b}|^2$

$\bar{a} \times \bar{b}=\bar{c} \times \bar{a}$
