Murty, Vedula N.; Swetz, Frank J. – Mathematics Teacher, 1982
An approach to how to expand explorations of determinants is detailed that allows evaluation of the fourth order. The method is built from a close examination of the product terms found in the expansions of second- and third-order determinants. Students are provided with an experience in basic mathematical investigation. (MP)
