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 counter-clockwise rotation of 90 degrees."
So for my answer, first I have for the reflection...
ok, maybe its not the cross product I need to do then.
The problem I'm struggling with is this:
"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 counter-clockwise rotation of 90...
How do I take the cross product of Two 3x3 Matrices.
For example what is cross product of:
[-1 0 0]
[0 1 0]
[0 0 1]
x
[0 -1 0]
[1 0 0]
[0 0 1]
thanks,
