joel:
How do i find the matrix which represents a transformation
shan2391:
i have the same problem refrence Q7b OCt08
zara:
very simple....
first draw the unit matrix n den watevr matrix is given draw dat...n den chk wat kinda transformation is hppning between the unit matrix n the one given...
hope u get it.. :)
shan2391:
zara can u plzz solve the Q7b in oct08
Ghost Of Highbury:
first write down 2 sets of co-ordinates from triangle T in a matrix form
then multiply it with the unknown matrix and equate it to the matrix form of two corrseponding sets of co-ordinates of the image i.e R
(2 8 ) * (w y) (-4 -4)
(4 4) (x z) = (-2 -8)
therefore you can find the values of w,x,y and z by multiplying (-4 -4) with the inverse of (2 8 )
(-2 -8) (4 4)
=> so the answer is (0 -1)
(-1 0)
plz infrm me if u didn't understand...as i am available anytime in studentforums...
Good luck
