Linear mappings: Linear mappings
Kernel and image of a matrix mapping
Let \(L_A: \mathbb{R}^3\longrightarrow \mathbb{R}^3\) be the linear mapping determined by the matrix \[A=\matrix{-7 & 3 & 19 \\ 21 & -9 & -57 \\ -7 & 3 & 19 \\ }\tiny. \] Calculate a vector \(\vec{v}\) that spans the image of \(L_A\).
\(\vec{v}={}\) |
