Looking for help with a problem I'm working on: "Show that matrix [0 1 0] [1 0 0] [0 0 1] for a reflection about line y=x is equivalent to a reflection relative to the y axis followed by a counterclockwise rotation of 90 degrees." So for my answer, first I have for the reflection relative to the y axis, I have the matrix: [1 0 0] [0 1 0] [0 0 1] and for the counterclockwise rotation of 90 degrees, I have the matrix: [0 1 0] [1 0 0] [0 0 1] but then I don't know what my next step should be. Can anyone help me with this? thanks, Della
