Points A and B are located at and respectively. Point C divides into the ratio . Find the coordinates of Point C.

Thanks... this is a hard one i think... maybe i need to brush up on my analysis

AB can be represented as (c-a,d-b)

since C divides AB in the ratio p:q,

C = A+AC

Thanks heaps badgerigar! I notice how you switched the ordered pairs from coordinate points into length units, that was smart.

This probably isn't that important seeing as the main aim has been achieved, but for all purposes shouldn't AB be (|c-a|, |d-b|)

So the final coordinates become

If you want to think about an example try A=(3,0) B=(0,0) and the ratio 1:2 - Dec 7th 2007, 11:16 PMDivideBy0
