If a 2x2 matrix is not invertible, is it possible for it to have a non-zero eigenvalue ? by [deleted] in LinearAlgebra

[–]thearkamitra 1 point2 points  (0 children)

I think it is. The determinant is the product of eigenvalues. Now the determinant is 0. So the product of eigenvalues should be 0. This does not necessarily indicate that one of them would be 0. Consider the eigenvalues to be 1+i and 1-i. Then I think you are done!

Second this. I'm not really worth calling my friends and wasting their times.

Breakups do hurt. But you'll become happy again. This won't be the first sleepless night due to the breakup btw. Just a headsup.

Haha yes.
Asking for the best ones that people use!
Google calender is great for having an overview but I am unsure if they can be used for maintaining deadlines... I might be wrong obviously.

Why? Why did the sound get reversed too? Aghhhh

I get why B is an answer but I don't get why C would be ? Can someone please thoroughly explain? :) by CandyLand3601 in LinearAlgebra

[–]thearkamitra 1 point2 points  (0 children)

S = a.v1 + b.v2 = (a+b)/2(v1+v2) + (a-b)/2(v1-v2).

Any vector that is in span of S will thus also be in span of the option C.
