syed1995 yeah i think so... i just remeberd lst year when we were on xpf for more than 12 hrs and so came again..
my subs are accel maths, physix, chem and eco

I kinda knew you will be giving accel maths.. cuz you were a maths guru in our days S1, M1?

How's the preparations for Chemistry and Physics.. because I know I don't need to ask about your Maths P1

nP..
bdW i also remember yu from the last year..

last msg was for daredevil
thanKX syed1995 ... mine are p1,p3,s1,s2
physix chem are goin well

in part ii find AB vector first:
AB = OB - OA
if OA is perpendicular to AB then the angle between them is 90 so :
OA . AB = 0
solve this out bcz i'm not doing it again or other people will post and post and post all the answers again
no really try it urself u'll b able to do it... if not then tell me

im not barking

ur question n mine is same....u just look above ur posts?

 

[Rutzaba]

MustafaMotani

AH YEAH.. I remember that question! It won't be solved with the dot product method.. try it .. it will blow your brains out and you won't be able to solve it.

One of our Add maths concepts is what is going to be used here

If Two Vector A and B are collinear (on the same line).. then Vector B = k(Vector A)

OA = p,1,1 OB = 4,2,p

Comparing the j coefficents ..

OB = k(OA)
2 = k(1)
k=2

now compare either of the first or last to get p... Like comparing the first one we get

OB = k(OA)
OB = k(OA)
4= 2(p)
p=2 Answer

ohhhhhh!
