Homework Statement
Find the standard matrix representation for each of the following linear operators:
L is the linear operator that reflects each vector x in R2 about the x1 axis and then rotates it 90° in the counterclockwise direction.
Homework Equations
The Attempt at a Solution
So my thinking is they wat a L.O that reflects any vector about the x1 axis. So for instance if we input a vector e1=(1,0) into our linear operator
L(e1)=(x1,-x2)
L(e1)=(1,0)T
Same goes for e2
e2=(0,1)
L(e2)=(y1,-y2)
L(e2)=(0,-1)
Here is where I get a bit confused. How do It ake in the 90° counter clockwise rotation into account?
