Best ResponseYou've already chosen the best response.0I think you mean the question 1I5. If you know the angle between a vector and xaxis, then you can get the vector's direction. In this question, draw a horizontal line L through point Q, the angle between QP and L is θπ/2, then we can find dir QP=<cos(θπ/2),sin(θπ/2)>=....
