The Cayley-Hamilton Theorem provides a method for calculating powers of a matrix. For example, if A is a 3x 3 matrix with the characteristic equation Co + Cz1 +C212 + 13 = 0 then col + c,A + C2A² + A³ = 0, so A3 = - C2A? - C1A – col Multiplying through by A yields A4 = - coA – c¿A² – C2A³, which expresses A“ in terms of A3, A² and A. Use this procedure to calculate A3 and A4 for 0. 1 0 A =| 0 0 1 1 -4 4

Question
The Cayley-Hamilton Theorem provides a method for calculating powers of a matrix. For example, if \( A \) is a \( 3 \times 3 \) matrix with the characteristic equation

\[ c_0 + c_1 \lambda + c_2 \lambda^2 + \lambda^3 = 0 \]

then \( c_0I + c_1A + c_2A^2 + A^3 = 0 \), so

\[ A^3 = -c_2A^2 - c_1A - c_0I \]

Multiplying through by \( A \) yields 

\[ A^4 = -c_0A - c_1A^2 - c_2A^3 \]

which expresses \( A^4 \) in terms of \( A^3, A^2 \), and \( A \). Use this procedure to calculate \( A^3 \) and \( A^4 \) for 

\[ A = \begin{bmatrix} 0 & 1 & 0 \\ 0 & 0 & 1 \\ 1 & -4 & 4 \end{bmatrix} \]

\( A^3 \) is

\[
\begin{bmatrix} 
\boxed{} & \boxed{} & \boxed{} \\ 
\boxed{} & \boxed{} & \boxed{} \\ 
\boxed{} & \boxed{} & \boxed{} 
\end{bmatrix}
\]

\( A^4 \) is

\[
\begin{bmatrix} 
\boxed{} & \boxed{} & \boxed{} \\ 
\boxed{} & \boxed{} & \boxed{} \\ 
\boxed{} & \boxed{} & \boxed{} 
\end{bmatrix}
\]
