With respect to the origin O, the position vectors of points A, B and C are (2, 3), (4, -2) and (-3, -3) respectively.
(i) A point E (-2, p) is such that 2 |CE| = |AB|. Find the possible values of p.
Ans: - 5 1/2 or -1/2
(ii) Find the coordinates of the point Q if 2 CQ = BA + 1/2 AC.
Ans: (-5 1/4, -2)
Please help by showing workings...thanks
Vectors...really need help...?
wtf?
