Numerical Analysis Questions & Answers  


I'll check again your quiz to be sure. The problem in your case is that you used the Simpson rule to get $I_i$: you shouldn't do this here hence why you got 2/3.




Good question. You should implement the algorithm so that dt is changed at the final step in order to yield t=tmax after the iterative process. 2 points bonus.




No, this is not what the question says. You can't change $N$: you need to keep it as even.




You should use the forward Euler method for part (a) and (b). I'm not sure what you mean by “part of error”. Why do you want to find the error?




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.
