Homework Statement
In the xy-plane, sketch the coordinate system [ a; b] corresponding to the basis
{ (1, 1 ) , (1, -1) } by drawing the lines a = 0, [tex]\pm[/tex]1 and b = 0, [tex]\pm[/tex]1. What point in the xy-plan corresponds to a = 1, b = 2?
Homework Equations
Not sure of any in this case
The Attempt at a Solution
I just stared at this Q in total blank.
After couple minutes, I tried to place the a and b coordinates like they were x and y coordinates respectively, and then line them up according to which one was a = 0, a = 1. Once again, had no clue what I was doing.
Had a look at the answer provided, and it looked like the attached provided. Tried to make heads and tails of it but doesn't really make much sense to me..
Any assistance would be greatly appreciated! =D
