\det(A)=\prod_{i=1}^{n}\lambda_iVariables
- Define every symbol and unit before substitution.
- Check the domain, shape, and convention required by the formula.
How to use this formula
Relates a square matrix determinant to its eigenvalues with multiplicity.
Important notes
- Verify assumptions and units before applying the expression.
- Keep exact values until the final rounding step when possible.
Quick example
Use the determinant as eigenvalue product with a small known example, then verify the result independently.
Applicability, worked calculation, and verification
Assumptions and domain checks
- For the Determinant as Eigenvalue Product, verify assumptions and units before applying the expression.
- For the Determinant as Eigenvalue Product, the index variable, lower bound, upper bound, and any empty-sum or empty-product convention must be clear.
- Preserve matrix order and verify dimension compatibility; multiplication and inversion are not generally commutative or always defined.
- Matrix and vector dimensions must be compatible, and any required inverse, determinant, rank, or basis condition must hold.
Worked example
Use the determinant as eigenvalue product with a small known example, then verify the result independently.
Common mistakes
- Do not omit the index or bounds in Determinant as Eigenvalue Product; changing either one changes which terms are included.
- Do not assume commutativity, invertibility, independence, or full rank unless the required condition has been established.
