Discussion area for final exam practice problems
This is the place.
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
