Find a vector orthogonal to both (-4, -2, 0) and to (0, -2, -2) of the form (1, -1 2Gandalf the Grey started in the Forest of Mirkwood at a point P with coordinates (3, 3) and arrived in the Iron Hills at the point ) with coordinates (5, 8). If he began walking in the direction of the vector v = 41 + 1j and changes direction only once, when he turns at a right angle, what are the coordinates of the point where he makes the turn? )
