When solving a 3 3 determinant I broke the determinant down into a sequence of 2 2 determinants, remembering to alternate the signs of the leading coefficients in front of the smaller determinants. By extension, how might I calculate a 4 4 determinant?
Please show all work thoroughly.
Also, what is the advantage of using the method of Substitution for solving a system of equations compared to using the method of addition?© BrainMass Inc. brainmass.com March 4, 2021, 6:16 pm ad1c9bdddf
This explains how to calculate a 4x4 determinant and explains the advantage of teh substitution method of addition.
