WebIf you dive into the linear algebra module (and you're more than able to handle it), you can see that this makes sense because a determinant of zero means that the row vectors are linearly dependent and therefore cannot span the entire space (but if you haven't gone into the linear algebra module yet, even that is gibberish). ^_^ ( 5 votes) Flag Webin this question, we have to expand the dominant dates using the third column. So determinate off able beak were to a 123 Cool factor off one tree less a Tucci Cool factor off 23 less a 33 Go back to Ralph G. Three and a 43 cool factor off 43 now a country and a 23 r zero.

WebIt means that you'll get the Taylor polynomial up to the term where you use the second derivative and elevate (x-c) to the second power. For example if instead of the second degree polynomial he used the third degree it would add: (f''' (2) (x-2)^3)/3! to the Taylor Polynomial.
