Best ResponseYou've already chosen the best response.0so for Px = P^1x... [0,1; 1,0]x = [0,1; 1,0}x each system row reduces to {1,0; 1,0}.... to prove for any vector in r2, I would use the a sub(subm,n) notation...that is the most simple example that I can give...the column vectors form an orthonormal set and because it is a square matrix, its inverse is also equal to its transpose.
