from part (d)(i) ,,we summed up that
AR=p+kBP
AR=p+k 1/2 p
and from the diagram we can tell that BR=4p
so p+4p =5 p or simply 5

(that's how i think it works)

Question 18, anybody can solve ?!?!

hey man i would like to help i know how to get this answer step by step! but i cant type it in here! :S but u can find ur solution in any IGCSE maths book under the TOPIC : Algebra, Chapter : Matrices. u will hopefully find ur solution there!

how can u say br is 4 p ? p is a vertical vector :/

Where is q? -.-

any luck yet?

WHAT A QUESTION??
i myself donno the answer...
but can u check ma answers
(a) p - 0.5q
(b) 1/3 p - 1/6 q
(c) 1/3 p+ 5/6 q
(d) (i) p + k/2 p
......(ii) 5

 

[GetSomeLife]

any luck yet?

Yep Got it!

AR = L(AQ)
p + kq/2 = L( (5/6)q + p/3)

Simplify as much as you can and you'll get:

2L(5q + 2p) = 6(kq + 2p)

L = 3

equate to get k = 5

Yep. They are all correct except that

(d) (i) p + kq/2 NOT whatever you wrote

i was doing the same but instead of taking a variable such as L i was taking k
nicely done bro

Yupiii......good....from where these papers?
both are same k/2 p = kp/2

 

[bluefa1con]

ok guys best of luck to every one
may Allah give us all success
pray for every one

 

[bluefa1con]

btw why are u solving gce paper
we have a different syllabus
