Linear Algebra

**Problem 1:**

Suppose \( T : \mathbb{R}^3 \rightarrow \mathbb{R}^3 \) is the transformation that:

- Reflects a vector across the \( xy \) plane,
- Then rotates it 90 degrees clockwise around the \( z \)-axis (if we take our perspective from above),
- And then scales it by a factor of 2.

Find the matrix \( A \) which represents \( T \). Then, find the inverse \( A^{-1} \) (hint: think about how to "undo" the transformation described above).

Then, compute the products \( A \ast A^{-1} \) and \( A^{-1} \ast A \) to show that your answer is correct.

Branch of mathematics concerned with mathematical structures that are closed under operations like addition and scalar multiplication. It is the study of linear combinations, vector spaces, lines and planes, and some mappings that are used to perform linear transformations. Linear algebra also includes vectors, matrices, and linear functions. It has many applications from mathematical physics to modern algebra and coding theory.
