Let i = 1 and let A = [ i 0 0 i ] and B = [ 0 i i 0]. (a) Find A2, A3, and A4. Identify
Chapter 8, Problem 109(choose chapter or problem)
Exploration Let \(i=\sqrt{-1}\) and let
\(A=\left[\begin{array}{cc} i & 0 \\ 0 & i \end{array}\right]\) and \(B=\left[\begin{array}{rr} 0 & -i \\ i & 0 \end{array}\right]\)
(a) Find \(A^2,\ A^3\) and \(A^4\). Identify any similarities with \(i^2,\ i^3,\) and \(i^{4}\).
(b) Find and identify \(B^{2}\).
Text Transcription:
i = sqrt -1
A = [ _0 i ^i 0]
B = [ _i 0 ^0 -i]
A^2, A^3
A^4
i^2, i^3
i^4
B^2
