Equation in b: n x (n+1) + (n+2)^2

Expand and simplify this to get 2n^2 + 5n + 4

Compare coefficients to obtain 2,5,4.

can u solve 16b as well

20a plzz explain and draw line i u can?

 

[exploded diper]

this is wrong :s i was referring to that 5y+.. question

what sthe question

 

[asadalam]

why in part (c) is the matrix showing the shear factor as -2???
and can someone solve the shear part for me plsss thnx....

You can simply apply the matrix to get the answer.

Shear towards the left is negative hence -2 and you just multiply the matrice with the coordinates of A.

now i get the negative thingy....
tyvm!

 

[Asad.Babur]

pathagoras theorum? hows it applicable here?

no, only matrices of order 2 * 2 are in syllabus.

It is a column vector!

because y axes is the invarient line wouldnt the object move downwards....as y axis is changing......

I really have no idea, I just read somewhere shear is negative if something is moving towards the left.

This will done from the graph, I think you have to check values of x when y= 0.

 

[Faizan Muhammmad]

whose all elements are a part of the other set.
yes, 2 ka cube is 8

faizan Muhammad, ^ according to this def. {} is improper, and (1, 2, 3) is a proper subset of the set {1, 2, 3). no?

ulta nae hogya?
proper subset is subset having atleast one item less than the super set
{1,2,3} is improper since it has all
{} should be proper since it has less
