Given matrix A=(1322) . [i] Use the cross-multiplication method to calculate the determinant of matrix A , i.e. find |A| . [ii] Find the inverse of matrix A , i.e. find A1 . Note:- You may use the short-cut method as discussed in Chapter 3. [b] Given matrix B=332100221 . [i] Find the co-factor matrix of matrix B . [ii] Choose a suitable row or column to expand in order to find the determinant of matrix B and explain why. Calculate the determinant of matrix B , i.e. calculate |B| based on this choice. Note:- A mark will be deducted if your choice is not the proper choice. [iii] Use your results from parts [i] and [ii] to find the inverse of matrix B , i.e. find B1
