Let A be a matrix with columns col1 and col2

Consider points T,U,V,W in the output grid below


Then what is the list \(\mathbf{A}^{-1} \overrightarrow{T}, \mathbf{A}^{-1} \overrightarrow{U}, \mathbf{A}^{-1} \overrightarrow{V}, \mathbf{A}^{-1} \overrightarrow{W}?\)

Let's see you have a go at this, making use of the answer I gave here: https://web2.0calc.com/questions/please-help-thank-you_42#r1

 

Note that

A-1 = [ 0  1]

         [-1  0]

 

T = [-1]

      [-1]

 

U = [2]

      [3]

 

V = [3]

      [1]

 

W = [ 2]

       [-1]
