hej Tommy Den linjära avbildningen \displaystyle F:{\bf R^3}\rightarrow{\bf R}^3 har i basen \displaystyle \underline{\boldsymbol{e}}=\{\boldsymbol{e}_1, \boldsymbol{e}_2,\boldsymbol{e}_3\} matrisen

\displaystyle A=\left(\begin{array}{rrr}0&1&2\\5&-1&0\\4&0&-2\end{array}\right)

a) Bestäm bilden \displaystyle \boldsymbol{u}=\underline{\boldsymbol{e}}\left(\begin{array}{r} 2\\-1 \\ 3\end{array}\right) under \displaystyle F. b) Ange urbilden till \displaystyle \boldsymbol{v}=2\boldsymbol{e}_1+5\boldsymbol{e}_2+2\boldsymbol{e}_3 under \displaystyle F.
