![**MATH 310**
1. Let \( e_1, e_2, e_3 \) be the standard basis vectors in \( \mathbb{R}^3 \) and consider the ordered basis:
\[
\{e_3, -e_1, e_2 + e_1\}
\]
Verify that this is actually a basis and find the coordinates of the vector \( (1, 1, 1)^T \) with respect to that basis.
2. Let \( T \) be the linear map from \( \mathbb{R}^2 \) to \( \mathbb{R}^2 \) defined by:
\[
T((x, y)^T) = (x - 2y, 2x + y)^T
\]
Find its matrix (with respect to the standard basis of \( \mathbb{R}^2 \)).
3. Let \( T \) be the linear map from \( \mathbb{R}^3 \) to \( \mathbb{R}^3 \) defined by the formula:
\[
T((x, y, z)^T) = (3x + y, 2x - z, y)^T
\]
Find the matrix of \( T \) with respect to the standard basis of \( \mathbb{R}^3 \).

**Detailed Explanation of Concepts**
1. **Standard Basis in \( \mathbb{R}^3 \)**:
The standard basis of \( \mathbb{R}^3 \) consists of the vectors:
\[
e_1 = (1, 0, 0)^T, \quad e_2 = (0, 1, 0)^T, \quad e_3 = (0, 0, 1)^T
\]
To verify that \( \{e_3, -e_1, e_2 + e_1\} \) is a basis, we need to show that these vectors are linearly independent and span \( \mathbb{R}^3 \).
