QUESTION:
Problem 1E
Use row operations to show that the determinants in Exercises 2–4 are all zero.
ANSWER:
Solution :
Step 1:
In this problem we need to show that the solution of the determinant is zero.
Determinant : the determinant is a useful value that can be computed from the elements of a square matrix . The determinant of a matrix A is denoted det(A), det A, or | A |
Rules of determinant :
1. Switching two rows or columns changes the sign.
2. Scalars can be factored out from rows and columns.
3. Scalar multiplication of a row by a constant multiplies the determinant by .
