9 The matrix \(\mathbf { C }\) is given by \(\mathbf { C } = \left( \begin{array} { r r } 0 & 3
- 1 & 0 \end{array} \right)\).
- Draw a diagram showing the unit square and its image under the transformation represented by \(\mathbf { C }\).
The transformation represented by \(\mathbf { C }\) is equivalent to a rotation, R , followed by another transformation, S.
- Describe fully the rotation R and write down the matrix that represents R .
- Describe fully the transformation S and write down the matrix that represents S .
