Homework Statement
Find the matrix for the transformation which first reflects across the main diagnonal, then projects onto the line 2y+√3x=0, and then reflects about the line √3y=2x
Homework Equations
Reflection about the line y=x: T(x,y)=(y,x)
Orthogonal projection on the x-axis T(x,y)=(x,0)
Orthogonal projection on the y-axis T(x,y)=(0,y)
The Attempt at a Solution
Reflection about the line y=x: T(x,y)=(y,x), so the standard matrix for this would be the matrix {(0,1),(1,0)}
However I'm not sure how to deal with equations rather than axis. I assume in the second projection, you can simplify it to y=√3/2 x. Can you then separate these into a scalar operation (√3/2) and orthogonal operation (y=x)? Even so, I wouldn't know how to go further than this since I only know how to do it among the axis
