Chapter 4.7, Problem 39E

Finding Transition and Coordinate Matrices In Exercises $37-40$, (a) find the transition matrix from $B$ to $B^{\prime }$, (b) find the transition matrix from $B^{\prime }$ to $B$, (c) verify that the two transition matrices are inverses of each other, and (d) find the coordinate matrix ${\left[x\right]}_B$, given the coordinate matrix ${\left[x\right]}_{B^{\prime }}$.

$\begin{array}{l}B=\left\{\left(1,0,2\right),\left(0,1,3\right)\left(1,1,1\right)\right\},\\ B^{\prime }=\left\{\left(2,1,1\right),\left(1,0,0\right)\left(0,2,1\right)\right\},\\ {\left[x\right]}_{B^{\prime }}=\left[\begin{array}{c}1\\ 2\\ -1\end{array}\right]\end{array}$
