Answer

The transformation is a clockwise rotation by 29 degrees.

Solution

We start with the given matrix: \[ \begin{bmatrix} \cos(-29^\circ) & -\sin(-29^\circ) \\ \sin(-29^\circ) & \cos(-29^\circ) \end{bmatrix} \] 1. The standard rotation matrix by an angle \(\theta\) is: \[ \begin{bmatrix} \cos \theta & -\sin \theta \\ \sin \theta & \cos \theta \end{bmatrix} \] 2. By comparing the given matrix with the standard form, we see that \(\theta = -29^\circ\). 3. A rotation by a negative angle indicates a rotation in the clockwise direction. Specifically, a rotation by \(-29^\circ\) is equivalent to a clockwise rotation of \(29^\circ\). Thus, the transformation represented by the matrix is a rotation by \(29^\circ\) clockwise.

Extra Insights

The transformation represented by the given matrix is a rotation. Specifically, the matrix corresponds to a rotation of \(-29^\circ\). Since a negative angle indicates a rotation in the clockwise direction, this transformation is indeed a clockwise rotation. For a quick cheat sheet: remember that in standard mathematical convention, positive angles indicate counterclockwise rotations, while negative angles indicate clockwise rotations. So, when you see a negative value like \(-29^\circ\), just imagine turning to your right!
