Explain how to answer this question:

Are the two linear transformations the same? 

Yes ✅

- **S: ℝ² → ℝ²**, shear such that \(\begin{bmatrix} 1 \\ 0 \end{bmatrix}\) maps to \(\begin{bmatrix} 1 \\ -\frac{1}{\sqrt{3}} \end{bmatrix}\) followed by shear such that \(\begin{bmatrix} 0 \\ 1 \end{bmatrix}\) maps to \(\begin{bmatrix} \frac{\sqrt{3}}{4} \\ 1 \end{bmatrix}\).

- **T: ℝ² → ℝ²**, rotate counterclockwise 150° about the origin, scale horizontally by a factor of \(-\frac{\sqrt{3}}{2}\), and then scale vertically by a factor of \(-\frac{2}{\sqrt{3}}\).
