what is the nature of solution if D=0
Answers
Answer:
Linear Algebra, using matrices as Cramer’s rule instructs, we use coefficient arrays to find the determinant. “D” is the value for the determinant that is used to test the answer for a series of equations, without having to do either the entire equation or the full set of matrices. It is a shortcut, if you will. And as long as the number of unknowns (equations) does not exceed 3, Cramer’s rule can be very handy, as long as D ≠ 0.
The reason is that since “D” is the denominator in the last equation, the answer would be, at best, “undefined” since one cannot divide by 0. Consequently, if D = 0, Cramer’s rule fails, as the determinant of the coefficient array is zero. Consequently, the system of equations then has either infinitely many solutions (indeterminate) or no solutions (it is inconsistent) In either case, you need some other method for finding a solution(s). Cramer’s rule will work if there is exactly one solution that is not “0,” but would be ineffective under all other circumstances
