The value of the determinant:
Answer to Problem 1E
Solution:
Explanation of Solution
Concept:
To find the value of a second order
To find the value of a third order
Step 1. Expand along the first row with signs alternatively
Step 2. Expand the second order minors to get the product:
Step 3. Simplify further:
Calculation:
The above is a second order
So by the given concept, it can be expanded as:
Simplify further:
Thus the value of the given determinant is
Conclusion:
Therefore, the required value of the determinant is
