Sep 25	comment	Diagonal Matrices with Zero on Diagonal Thank you. Yeah, I just wanted to make sure that these are diagonal as well as I need to prove that they are zero divisors.
Nov 28	comment	Proof by Induction: Alternating Sum of Fibonacci Numbers My question was a little more specific, don't you think? I knew it was induction, I just didn't know where I went wrong in my proof.
Nov 27	comment	Proof by Induction: Alternating Sum of Fibonacci Numbers Thanks! I'm on SO a lot and I know people hate those "gimme the codez" kind of questions so I try to show what I've done as much as I can so that I'm not simply taking advantage of the community.
Nov 27	comment	Proof by Induction: Alternating Sum of Fibonacci Numbers It certainly helps when you try to prove something that's true x)
Nov 27	comment	Proof by Induction: Alternating Sum of Fibonacci Numbers Thank you. I was originally just adding 1 to the subscript instead of to the $n$. I also didn't realize that I needed to repeat both the $-f_{2k-1}$ and the $f_{2k}$ with the $+1$ to $k$. Your answer helped me find where I was going wrong!
Nov 26	comment	Proof by Induction: Alternating Sum of Fibonacci Numbers Thank you very much, I did not notice this
