We know from class that computing the determinant of an n × nmatrix using LU decomposition has computational cost W = O(n^3).But how expensive is it to compute a determinant using the commonrecursive definition formula for determinants?

(a) Determine the number of floating point operations required for calculating the determinant of an n × n matrix using a straightforward implementation of the recursive definition of the determinant. (You can combine additions and multipli- cations.) Hint: consider the number of flops done on each recursive level separately. How many determinants are to be computed on each recursive level? On each recursive <div class=
