Question

Gandalf the Grey started in the Forest of Mirkwood at a point with coordinates (1, -3) and arrived in the Iron Hills at the point with coordinates (3, 1).If he began walking in the direction of the vector V=3i+2j and changes direction only once, when he turns at a right angle, what are the coordinates of the point where he makes the turn

Answer 1

This deals with vector projections. Let's make the following decla- rations: c < 2,4> U< 3,2 > C v So just calculate a, and then you can find b. 42 28 a13' 13 14 Thus, 42 28 13' 13 55-11 13' 13 So this person takes a turn at the point , I taught myself LIEX to make this clear.
