Given points A(4,3)A(4,3) and B(−1,5)B(-1,5). The orthonormal coordinate system is (O,I,J)(O,I,J), so I(1,0)I(1,0).

1. Détermine les coordonnées des vecteurs AB⃗\vec{AB} et 7AI⃗7\vec{AI}.

  1. Calculate the coordinates of AB⃗\vec{AB}.

    The coordinates of AB⃗\vec{AB} are (xB−xA,yB−yA)(x_B - x_A, y_B - y_A).

    AB⃗=(−1−4,5−3)=(−5,2)\vec{AB} = (-1 - 4, 5 - 3) = (-5, 2)

  2. Calculate the coordinates of $\vec
