Find the dimension of the subspace
Zhumagali S.
In each part, let $T_{A}$ be multiplication by $A$ and find the dimension of the subspace $R^{4}$ consisting of all vectors $\mathbf{x}$ for which $T_{A}(\mathbf{x})=\mathbf{0}.$ (a) $A=\left[\begin{array}{rrrr}1 & 0 & 2 & -1 \\ -1 & 4 & 0 & 0\end{array}\right]$ (b) $A=\left[\begin{array}{rrrr}0 & 0 & 1 & 1 \\ -1 & 1 & 0 & 0 \\ 1 & 0 & 0 & 1\end{array}\right]$
