Unformatted text preview: B-' in terms of A, C and D. 5. (20 pts.) Find the matrix representation of the linear transformations between R2 and R2 which i. Rotates points counterclockwise around the origin by 45 degrees. ii. Reflects points across the line xl = 22. iii. First rotates points counterclockwise around the origin by 45 de- grees and then reflects the resulting point across the line xl = 22. Apply all three transformations to (-4,l)....
