Consider the tridiagonal matrix

1. Why do we know that Naive Gaussian Elimination will work to solve the system of equations Ax→ = b→ where

for any
?
2. Solve the system of equations Ax→ = b→ where

using Naive Gaussian elimination
3. How do we know that the eigenvalues of A are all real and distinct before we calculate them?
4. Find the characteristic polynomial of A.
5. Find the eigenvalues of A. Hint: The characteristic polynomial can be easily factored into the product of two linear terms and a quadratic that you use the quadratic formula on.
