1 0 = 3 1 , so the standard matrix of Tis T(e 1) T(e 2) = 1 3 0 1 . 2. Ex. 1.9.11: A linear transformation T: R2!R2 rst re ects points through the x 1-axis and then re ects points through the x 2-axis. Show that T can also be described as a linear transformation that rotates points ................
