Numerical Analysis Questions & Answers  


Yes, you're on the right track. You should not be using at all the exact solution.




That was a question asked to you in one assignment problem. I can not give you the answer directly to an assignment question.






Your questions are not clear to me. To find $U$, we do not perform Gaussian elimination. Gaussian elimination is when solving $AX=B$ with $A$ given and without going through $L$ and $U$ matrices.




Yes.




You can come on Monday in the afternoon.
