Answer: Orthogonal Diagonalization In Exercises 4352, find a matrix P such that PTAP
Chapter 7, Problem 50(choose chapter or problem)
In Exercises 43–52, find a matrix P such that \(P^{T} A P\) orthogonally diagonalizes A. Verify that \(P^{T} A P\) gives the correct diagonal form.
\(A=\left[\begin{array}{rrr}
-2 & 2 & 4 \\
2 & -2 & 4 \\
4 & 4 & 4
\end{array}\right]\)
Text Transcription:
P^T AP
A=[-2 2 4
2 -2 4
4 4 4]
