Ghost Of Highbury:
The whole question or any subpart?

Ghost Of Highbury:
7)a)i) T(A) means to apply the transformation T to the point A. As T is a vector translation u can simply add the respective co-ordinates to get the co-ordinates of the image after the translation. (2) + (3) = (5)
                                                           (1) + (2)  = (3)

Therefore the answer is (5,3)

7)a)ii) Now, MT(A) means to apply the transformation T first and then apply M to the new image.
         After applying T , the image's co-ordinates are (5,3)

         M is reflection in the line y=x. First, draw the line y=x, reflect the point. The new co-ordinates shud be (3,5).

        PS : Wenever a point on the cartesian plane is reflected in the line y=x, the image co-ordinates are actually the inverse of the object co-ordinates.

7)b) This is a direct question . Answer : (0 1)
                                                      (1 0)

       U can find the list here : https://studentforums.biz/index.php/topic,5575.msg167872.html#msg167872    (3rd message)

7)c) For this u have to do the transformation mentioned in the q i.e TM(Q)
       
       So, M(Q) = (k-3, k-2)   (Remember the reversing method)

      T(k-3, k-2) = ((k-3) + 3, (k-2) + 2) = (k,k)

       The y-co-ordinate of the image is k, and the x-co-ordinate of the image is also k. Thus its always on the line y=x..

7)d) The inverse of the identity matrix remains the same,

7)e)i) N = (0 4) - (0 3)  = (0  1)
              (0 0)   (1 0)     (-1 0)

7)e)ii) Check the list : https://studentforums.biz/index.php/topic,5575.msg167872.html#msg167872

          rotation 90 degrees clockwise around centre (0,0)

Vin:
OMG!!!! THANK YOU SO SO MUCH FOR YA HELP !! :D :D
really u've made my day! :) :P
awesome didnt expect ny1 to do this for me
thanks again!!:):)
By the way the links are really good.. ;D

Ghost Of Highbury:
No trouble.

or u can remembr it this way "ALL SILVER TEA CUPS"
ALL: all
SILVER: only sine
TEA : only tan
CUPS: only cos
    :) :) :) :) :) :) :)
