Linear mappings: Linear mappings
Finding the matrix that determines a linear mapping
The linear map \(A \) from \( \mathbb{R}^2 \) into \(\mathbb R^2\) satisfies
\[\begin{aligned}
A\cv{3\\-3} &= \cv{12\\6}\\
A\cv{-3\\-3} &= \cv{-12\\24}\tiny{.}
\end{aligned}\]Determine the matrix of \( A\) with respect to the unit vectors.
\[\begin{aligned}
A\cv{3\\-3} &= \cv{12\\6}\\
A\cv{-3\\-3} &= \cv{-12\\24}\tiny{.}
\end{aligned}\]Determine the matrix of \( A\) with respect to the unit vectors.
