hahaha---i think that is under binomial i guess---i am an IGCSE student--sorry

 

[Min Thaw]

binomial?..really...i thought i had to do with "sequences and series" and one of my friend got the answer too with that method..
binomial would be another awesome alternative...
but please elaborate more if you dont mind...just some short briefs..
thanks again

 

[aniekan]

is it 2 root 499 or 499 root 2-------it can also be solved with binomial but as a IGCSE student i doubt if i can elaborate on it---i will be able to do that next year

 

[Min Thaw]

is 2 power 499 XP
is ok..is my pleasure that you answer

 

[aniekan]

you are welcome--wish i could enlighten you on it

I have problem with vectors xD:
1- The point A has coordinates (1.2) and the point B has a coordinates (4.7)
a) i) Find AB
ii) Find the magnitude (here is the question)

2-PQRS is a parallelogram
M is the midpoint of QR
PQ= a and PS=B
a) Find in term of a and b an expression for PM
T is the point on SR extended such that Sr=RT
b) i) Find in terms of a and b an expression for PT
ii) use your answer to part i) to prove that P,M and T lie on the same straight line (here is the question)

Thanks in advance and waiting for answer

SORRY PM=1/2PT OR PT=2PM

 

[Stancy Motha]

binomial in IGCSE???
I am taking the same test.. y haven't I heard of it before??just askin....

 

[Min Thaw]

you are kiddin rite?

 

[Stancy Motha]

no no no...we haven't done a single thing concerning it...
ok wer's the qp from

 

[Min Thaw]

um..i think i messed up... you don't take FURTHER PURE MATHEMATICS right?
then..yeah..there is no binomial in Maths...
sry to make you worried

 

[mahmoud631]

SORRY PM=1/2PT OR PT=2PM

Many thanks for your kind and fast reply I really appreciate this.
But please I can't understand why RT= a

 

[Stancy Motha]

Mathematics syllabus-B
ha ha np

 

[mahmoud631]

Thats syllabus A xD

 

[Min Thaw]

here's a question < not concerning with exams > : Why do we find mid-point of line <median> when solving 3D geometry?
i hope you guys know what my question means...
