Consider the following plane with the both the red and black coordinate systems. The red axes correspond with what are normally thought of as the lines y = 4x and y=-x. Let the two red vectors highlighted Call the standard = {[²].A} along the red axis be the basis vectors for a new "red basis," called R = basis B.

and D are the stretch matrices in black and red respectively, and P renames vectors from red to black:
[x]a
P↑
[x]r
A
D
A[x]a = [y]a
|P
D[x] = [y]r

each of these, give at least one sentence explaining how you found them.
ii. Pick either question 1ci or question 1cii above and explain, using the above diagram, how there are
two different methods in which you could have found the answer to that question.
