comment Prove that the nxn all 1 matrix (apart from diagonals which are 0) has -1 as an eigonvector with multiplicity n-1
Please write the full details of the question in the actual question, not the title, it is rather unclear like this.

Oh my, I really do need to study Taylor series properly.

Dammit, thanks for that. I've always been bad at inequalities ever since high school :>

comment Matlab, “tranpose(x)” not doing it right?
Haha, I remember when (not so long ago) I first found out that vector*vector=matrix, I definitely took a bit of time (and thinking) to digest that.

comment Confused with a limit
As this is a homework question, depending on the ammount of rigour in your course, you might have to specify that you're using the limit of a composite function theorem (and why you can apply it).

comment Probability of rolling a “1” on a die conditioned on when all rolls are different.
Ahh, the first way is so perfectly clear and efforetlessly true once I read it, any tips on how to see that in a question like this?

Yes, that's right. However, make sure you check drhab's and Austin's answers, too, they provide a different (and possibly even more insightful) way of thinking about the question :)
