Question

Fie ABCDEF un hexagon regulat. Daca AB = u(vector) si BC = v(vector) calculati CD(vector) in functie de u si v

Astept un raspuns va multumesc anticipat

Answer 1

$\it \overline{AC} =\overline{AB}+\overline{BC} \Rightarrow \overline{AC} =\overline{u}+\overline{v}\\ \\ \overline{CD}=\overline{DA}+\overline{AC}=-2\overline{v}+\overline{u}+\overline{v}=\overline{u}-\overline{v}$
