In the case above, the standard matrix A for T:
T= [0 1]
[-1 0]
What is linear transformation about?
A linear transformation is known to be a kind of a function that exist from one vector point to another and it is one that often respects the linear) structure of all of vector space.
Note that in the linear transformation;
T: R² R²
T= (x, y), (-x, y)
Since:
(x,y) - (x,-y) - (y,-x)
A= [-1 0]
[0 1]
A= [-1 0] = A= [-x]
[0 1] [y]
Then [tex]T_{b}[/tex] is the reflection of (x- y); Since;
B = [0 1]
[1 0]
Then [tex]T_{B} (T_{a}(x) )[/tex] = [0 1] = A= [-x]
[0 1] [y]
= [-x]
[y]
Then: T: = [0 1] [x]
[0 1] [y]
Therefore, In the case above, the standard matrix A for T:
T= [0 1]
[-1 0]
