In parts a and b, A is a matrix representation of a linear
transformation in the standard basis. Find a matrix representation
of the linear transformation in the new basis. show all steps.
a. A = 2x2 matrix with the first row being 2 and -1, and the
second row being 1 and 3; new basis = {<1, 2> , < 1, 1>
}
b. A = 3x3 matrix with the first row being 2, 1, -1, the second
row...
