In this question, we have for step 1 translate the triangle such that the scaling point 4, 3 coincide with origin.
00:17
So, th is equals to matrix of 1, 0, tx, 0, 1, ty, 0, 0, 1 is equals to 1, 0, negative of 40, 0, 1, negative of 30 and 0, 0, 1.
00:45
Now, scaling the triangle at new origin, then the matrix will become s is equals to sx, 0, 0, 0, sy, 0, 0, 0, 1 is equals to 2 .4, 0, 0, 0, 2 .4, 0 and 0, 0, 1.
01:16
Now, further step 3 includes inverse translation which means th of inverse is equals to 1, 0, 4, 0, 1, 3, 0, 0, 1.
01:42
Step 4, composite transformation matrix, ct is equals to th inverse s and th.
02:11
Therefore, we can write that the matrix will become 1, 0, 4, 0, 1, 3 and 0, 0, 1.
02:22
As we have that is 2 .4, 0, 0, 0, 2 .4, 0, 0, 0, 1 and the value of this th is 1, 0, negative of 4, 0, 1, negative of 3, 0, 0, 1.
02:41
Now, on solving those we get 1, 0, 4, 0, 1, 3, 0, 0, 1.
02:53
Further we get over here is 2 .4, 0, negative of 9 .6, 0, 2 .4, negative of 7 .2, 0, 0 and 1.
03:09
Now, if we going to solve this further then we get 2 .4, 0, 5 .6, negative, 0, 2 .4, negative of 4 .2 and 0, 0, 2...
