Namely a matrix $ \left ( \begin{array}{cc} a & b \\ c & d \end{array} \right ) $ acts by $ \left ( \begin{array}{cc} a & b \\ c & d \end{array} \right ) \cdot \left ( \begin{array}{c} u \\ v \end{array} \right ) = \left ( \begin{array}{c} au + bv \\ cu + dv \end{array} \right ) $. I thought it was obvious :) | |
