Note:
- The T1 translation is continued by T2 translation equal to T2 translation followed by T1 translation, ie (T1 o T2) = (T2 o T1). So the composition of two translations is commutative.
- The map shadow of A(x, y) by T1 translation is continued by T1 translation denoted by (T2 o T1) A (x, y).
Example:
Translations T1 and T2 each have column vectors (2 -3) and (-5 4), find (T2 o T1) A (-5, 1)!
