Figure 8.1.2.1

Representation of the point X with respect to origin O by the vector $[\overrightarrow{OX} = {\bf x}]$ . The vector x is described with respect to the vector basis $[\{{\bf a}_{1},{\bf a}_{2}\}]$ of $[{\bf V}^{2}]$ by the coefficients $[x_{1},x_{2}]$ . The coordinate system $[(O,{\bf a}_{1},{\bf a}_{2})]$ of the point space $[E^{2}]$ consists of the point O of $[E^{2}]$ and the vector basis $[\{{\bf a}_{1},{\bf a}_{2}\}]$ of $[{\bf V}^{2}]$ .
