Ms must be wrong,check the er.

MS is wrong. -.-

AM I RIGHT, NOW? *Sigh*

Yup...how did were u able to figure it out ,I mean of course u used the vector concept ,any other concept?

Now see this. Question 11b ii.

look at er it says -7 though
so misprint in ms

Do post the solution too, I read the part tried it a few times and left it k aisa sawal paper main nae ayega

Second one:
-3+17=14
9+K=4

Rearrange nd K will become -5

Add QP + PS and then compare with QU to get a factor of 2 to multiply with.

Thanks both of you.

Of course not in pprs,pretty lengthy u know
Well dark destination found the correct answers;he will post the solution .wont u Dark Destination ..Not now coz it will probably be lengthy but anytime tomorrow.

its lengthy?
I thought it must be a new small technique as the question looked pretty simple
Add math kee dafa sochain gay, uss main phir bhee a sakta hai :/

Hey u read many books I reckon.Haven,t u learnt to not judge a book by its cover.
Well the technique will not be a novelty of any sort just knowing when and where to use it ...Two basic techniques:One is the vect addition and subtr and manipulation 2nd one is also simple though has to be used on many occasions

You are giving add maths too this session?

Just a trivial point:how do u indicate plotted points on a graph..I mean for the polygon in P1 I used enlarged dots to indicate the points..wht did u do for tht...Plus in the graphs(including curves) is it better to use a cross,X, or they can both be equally suitable

Q9,b,iii

I used crosses cuz i read in an er of physics that we should use neat crosses.

Q9,b,iii

Part (a) tells you the vol. of the pyramid
Part (b) tells you the Base Area

Volume of pyramid = 1/3 * (Base Area) * HEIGHT

Substitute the values and find the HEIGHT

I have a question

The transformation B maps (1,0) onto (1,3) and (0,1) onto (-3,-2)
Write down the matrix that represents the tranformation B

Can someone please write down the order of the points included in the transformtion (ie. I don't know if it should be like this;
(1 ..... -3)
(3 ..... -2)

Or this

(1 ...... 3)
(-3 .... -2)

The above one.Since identity matrix is
(1....0)
(0...1)
and the points are of identity we can simply replace them to get the transformation matrix.1st one is right.
