TopicLinear transformations

1. $$\mathbf { P } = \left( \begin{array} { r r } 0 & - 1
1 & 0 \end{array} \right) \quad \mathbf { Q } = \left( \begin{array} { l l } 1 & 0
0 & 3 \end{array} \right)$$
    1. Describe fully the single geometrical transformation \(P\) represented by the matrix \(\mathbf { P }\).
    2. Describe fully the single geometrical transformation \(Q\) represented by the matrix \(\mathbf { Q }\). The transformation \(P\) followed by the transformation \(Q\) is the transformation \(R\), which is represented by the matrix \(\mathbf { R }\).
  1. Determine \(\mathbf { R }\).
    1. Evaluate the determinant of \(\mathbf { R }\).
    2. Explain how the value obtained in (c)(i) relates to the transformation \(R\).
