QUESTION 9 Define a transformation T by T(x) Ax where A Describe geometrically the effect of the transformation T O Projection onto x2-axis O Horizontal shear O Vertical shear O Projection onto x1-axis
A 2 x 2 matrix A is associated with the transformation that reflects vectors in the plane across the line y = 2x. Sketch the vector field (use your discretion and draw vectors until you believe that you have captured the big picture) corresponding to A. In other words, for every ~w, we place A ~w at the head of ~w.
