Question 1
Find the standard matrix for the following composition of linear transformation.
(a) A reflection about the x-axis followed by a rotation of 30°, in R².
(b) A reflection about the xz-plane, followed by an orthogonal projection on the yz-plane, and followed by a dilation with a factor of 3, in R³.
Question 2
Find the standard matrix for the transformation T : R³ ā R³ defined by the equations
wā = xā - 2xā + 2xā
wā = 2xā + xā + xā
wā = xā + xā
Then find Tā»Ā¹ < 2,5,2 >.
