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
\[\begin{aligned}
A\cv{1\\3} &= \cv{7\\2}\\
A\cv{1\\-1} &= \cv{-1\\6}\tiny{.}
\end{aligned}\]Determine the matrix of \( A\) with respect to the unit vectors.
\[\begin{aligned}
A\cv{1\\3} &= \cv{7\\2}\\
A\cv{1\\-1} &= \cv{-1\\6}\tiny{.}
\end{aligned}\]Determine the matrix of \( A\) with respect to the unit vectors.
