Lesson 4

Question 1

It fails for the system of equations in which D = 0 since for finding the values of unknowns, D must be in the denominator and hence these values go undefined.

Answer 1

Cramer’s rule

Question 2

It is the most familiar method for solving a system of linear equations. It consists of two parts which are elimination phase and solution phase.

Answer 2

Gauss Elimination

Question 3

It is the refinement of the Gauss elimination method.

Answer 3

Gauss-Jordan method

Question 4

It is a procedure for converting a matrix to reduced row echelon form using elementary row operations.

Answer 4

Gauss-Jordan elimination

Question 5

It is one of the iterative methods for approximating the solution of a system of n linear equations in n variables.

Answer 5

Jacobian method or Jacobi method

Question 6

It is an iterative method used to solve a system of linear equations. It is similar to jacobi method.

Answer 6

Gauss-seidel method
