I think 1/If we get Q(a,b,c) >> a,b,c are the co-ordinate of the POIN Q 2/If we get vector(Q(a,b,c)) >> a,b,c are the co-ordinate of vector(OQ), with O(0,0,0) I agree with you 100% in this kind, may be i understand Q = POINT, but u want to mean Q = vector in your solving :)

Disagree with the symbol of AKG, remember POIN is a non-direction Quantity, so that u can't use the VECTOR symbol . And your answer is right. When u take Q-P u will get the vector(PQ) , and the same with R-Q :)
