Discussion area for final exam practice problems
On problem 2, I noticed that in matrix form, both i and ii had one column that had a common multiple (1 for the 3rd column of i and 3 for the 3rd column of ii). Is that a quick way to see that they are not independent or does that not always hold true? I can quickly see that i has a det of 0 and calculated ii to get the same - I was just wondering if there's a quicker way? Thanks, Tlouvar
Nevermind. I changed the 7 to an 8 on ii and did not get a zero determinant, so I've answered my own question above. Tlouvar
Is there a place in the book that talks about #20 in the practice problems? It wasn't obvious to me how to calculate the coefficient and was seeing if there was a place I could read up on it.
From Steve Bell: I mentioned in my last review that there won't be any questions about complex Fourier Series on the Final Exam. There might, however, be questions about the complex Fourier TRANSFORM.
Just to confirm I'm doing this right. For number 16, I'd take the Laplace transform of each side, solve for Y(s), then do the inverse Laplace transform of Y(s), then plug in 2 for t?
Disregard, I answered the question for myself.
For #15, Shouldn't the answer be A? I'm confused where the e^2 comes from.
