Question
**Problem 3: Consider Linear Operators on \( \mathbb{R}^2 \)** Find the matrix representation of each: a) **Rotation of \(-30^\circ\):** Determine the matrix that represents a rotation of an angle of \(-30^\circ\) in the plane. b) **Reflection Across the \( x \)-axis:** Identify the transformation matrix for reflecting vectors across the \( x \)-axis. c) **Projection onto the \( y \)-axis:** Calculate the matrix that projects vectors onto the \( y \)-axis. d) **Composite Transformation \( T \):** Let \( T \) be a linear operator on \( \mathbb{R}^2 \) that performs the following sequence of operations: - Maps any vector to its reflection across the \( x \)-axis. - Rotates the resulting vector by \(-45^\circ\). - Projects the final image onto the \( y \)-axis. **Task:** Find the matrix representation of \( T \) by using the answers from parts (a), (b), and (c). Apply these transformations sequentially and provide the resulting matrix by multiplying the matrices obtained previously.
