OAB is a triangle, Qis the point of trisection of AB closer to B and on OQ such thaPOQAP produced meets OB at R. Express AP in terms of a and b, and hence find the number k such that OA +kAP does not depend ona Use your answer to express r in terms of b, and interpret this geometrically Use a similar method to identify the point S where BP produced meets OA
Please how to Express r in terms of b

Looks good so far, just sub K back into the OA+KAP expression to get
r = OR = ...
r = OR = ...

Yah it will give me right answer but I d
Yes it gave me the correct answer but I don't understand why. What is the relationship between r and OA+KAp

You found the value of K such that the expression only depends on b, i.e. where the b vector intersects with the line. It must be r.
