# Linear Transformation Problem: Finding Standard Matrices

In this exercise, we aim to determine the standard matrices \( A \) and \( A' \) for the composed transformations \( T = T_2 \circ T_1 \) and \( T' = T_1 \circ T_2 \).

### Given Transformations

- **Transformation \( T_1 \):**

  \( T_1: \mathbb{R}^2 \to \mathbb{R}^2 \)

  Defined by:
  \[
  T_1(x, y) = (x - 3y, 3x + 3y)
  \]

- **Transformation \( T_2 \):**

  \( T_2: \mathbb{R}^2 \to \mathbb{R}^2 \)

  Defined by:
  \[
  T_2(x, y) = (0, x)
  \]

### Task

- **Find the standard matrix \( A \) for \( T = T_2 \circ T_1 \).**
  
  The composition implies first applying \( T_1 \), then \( T_2 \).

- **Find the standard matrix \( A' \) for \( T' = T_1 \circ T_2 \).**

  The composition implies first applying \( T_2 \), then \( T_1 \).

### Diagram Explanation

- The diagram displays two blank 2x2 matrices labeled \( A \) and \( A' \). These matrices need to be filled with the coefficients representing the standard matrices of the transformations \( T \) and \( T' \).

- **\( A \)** and **\( A' \)** each consist of:
  - Two rows of two placeholders.
  - Green arrows pointing right signify the positions to fill for the output vector.
  - Green arrows pointing down indicate input dimensions processed during matrix multiplication.

The exercise requires calculating and inputting the correct values in these matrices based on the composition of \( T_1 \) and \( T_2 \).
