Carry out the following matrix multiplications. For each problem, say what the function
represented by each matrix does to the standard basis vectors and what the product of the two
matrices would do to these vectors.
a. =
b. =
c. =
Multiplying any matrix in 2-D by vector [1,0] gives the first column of the matrix and
multiplying it by a vector [0,1] gives the second column of the matrix.
