Homework Statement

Find the transition matrix from B to C and find [x]_C

B = {(3,1), (-1,-2)}
C = {(1,-3),(5,0)}

[x]_B = [-1 -2]^T

Well, if you call your transition matrix T, then

\begin{pmatrix} 1 \\ -3 \end{pmatrix}= T \begin{pmatrix} 3 \\ 1 \end{pmatrix}

and

\begin{pmatrix} 5 \\ 0 \end{pmatrix}=T \begin{pmatrix} -1 \\ -2 \end{pmatrix}

\Rightarrow \begin{pmatrix} 1 & 5 \\ -3 & 0 \end{pmatrix}= T \begin{pmatrix} 3 & -1 \\ 1 & -2 \end{pmatrix}

...is that enough to get you started?
