Exercise 3 Construct a 2 x 2 matrix Aq that performs a horizontal shear transforming , into 2+2 , (leaving , unchanged). Then, write a Python code to visualize the matrix transformation. Exercise 4 Construct a 2 x 2 matrix A2 that performs and reflects vectors through the line y = X. Then, write a Python code to visualize the transformation. Exercise 5 Write a Python code to compute A = AjA2 and visualize the matrix transformation A , where A, and A2 are the matrices obtained in Exercise 3 and 4
