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?

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.
