Hey for the Qu 9 what have u write guys? I think that the question is about which point is nearer to the point C.

i think that it was O nearer

any1 remembr ans of vector OA multiplied by vector OB?.....jst the product of the vectors

10

 

[kevin24]

Y not the point B? for the Qu 9

 

[Sanjay mitra]

What may be the grade threshold for today?

 

[kevin24]

What may be the grade threshold for today?

I pray God its less than 58 !

 

[kevin94]

Y not the point B? for the Qu 9

I dont know
i substituted x=0 in equation found. then i just observed which value was nearer to the y i got

but maybe i made a mistake
i got 1/1/3 but someone else got 1/2/3

 

[kevin24]

I went on using distance formula finding the distance OC and CB which I got 5/3 and 4/3 respectively. Then comparing these two I answered B. But I used too much time on this as it was only 1 mark.

I hOPE 56 ABOVE A N 48 ABOVE B......AS TODAY QUESTIONS WE DIFFICULT...

n for unit vector i got 2/3 and -1

Yea me 2

 

[mehdi1028]

for binominal what was A?? was it 2??
and what was the domain for q2

i think greater or equal to 1

any1 remembr ans of vector OA multiplied by vector OB?.....jst the product of the vectors

The angle between them was 21.4 right??

 

[mehdi1028]

i think the paper was more challenging than may/june 2012 (12)

No it was much easier ... Fist 9 questions were very easy

One distance was 4/3 and one was 5/3

You just needed to calculate the y-ordinates..

 

[mehdi1028]

A would be around 58 or 59

 

[Gunner7]

Yea me 2

How did you solve it please ?

 

[mehdi1028]

How did you solve it please ?

The magnitude of a unit vector is always equal to 1 ...
