oh sorry for wrong section, I am new to this forum...

Homework Statement Ok I was working with finding Jordan canonical form... Here is the matrix I was working on: | 1 1 1 | |-1 -1 -1 | | 1 1 0 | I am having problem with finding eigenvalues... below is the attempt to solution I was not getting the right answer. So, when I used...

The sequence (xn) is said to converge to a real number a. if for all ε>0, there exists N in N such that |xn-a|<ε for all n≥N.

Show there exist a natural number n... 1. Let {xn} be a sequence of reals which converges to x > 0. Show that there is a natural number n0 such that xn > 0 for all n >= n0 . I tried this but cannot approach the answer. Can anybody?
