Hello (pardon if it is in the wrong section, think it suits under trigonometry... Or should it be under... no clue! )

A transformation matrix is given by K as :

___ 1 2 0

K = 0 1 0

___0 0 1

Draw a square in the R2 panel with the coordinates:

A: 0,0

B: 1,0

C: 1,1

D: 0,1

Which is like this:

Now use the transformation matrix K on all four coordiantes (A,B,C and D). Now draw the square again with the new coordiantes.

Any suggestions on how I shall use the K on coordinate A?

What I think: I am moving A from (0,0) to (1,1), then I double the x-axis which makes A located at (2,1) after the transformation is performed, right or wrong? It isnt that simple?

Want just a suggestion on how to get started...
