Numerical Analysis Questions & Answers  




Good question. We need to find $b_N$ because $a_{N1}$ and $c_{N1}$ depend on $b_N$. So, we only need to find $N1$ intervals, but we need to find $N$ bs. 2 points bonus.




Hm, I'm not sure what confuses you. Answers to your questions were given in class.




There's little work involved when moving numbers around in memory compared with additions or multiplications. Hence why it's not counted. 1 point bonus.




You can find the exact value by using a very large $N$. So, just double $N$ until the value of the integral doesn't change significantly anymore and use this as the exact value. 2 points bonus.




No, there is no work done when doing the pivoting operation because there is no addition or multiplication. This was mentioned above for a similar question.
