In question one (b) why did you choose the two points PR and PQ Rather than PR and QR?how do I know what points should I choose? I'm confused!

[RawMaths]

To get from A to B you need to go back down a in the opposite direction which makes it negative then along OB in the correct direction which makes that positive b

[rosaarmstrong]

wait why does PA mean P, Q and R are co linear on the second question? What does PA have to do with it?

[chenelle]

In the first question, why is AB -a + b when you are going in the same direction as a shouldn't a be positive and b be negative? Thabks for the video

morning and good explanation most of the way

there is an error on the last part of question 2

surely you mean PQ rather thsn PA  is co linear to PR  ???

since vector AP = 1/5 a     multiples of this would have to be  of a similar (2/5 a) for example


Logically the lines PA and PR  cannot be going in same direction

otherwise proof is all good

if i'm wrong then please correct me

regards

why is BR 3/5b, i swear its supposed to be 3/8

[DeepakSingh-qvvz]

this is really confusing, he is mainly talking to himself throughout the working out and I get confused how he completes the question.
