[SOLVED] Nilpotent matrices 1. The problem statement, all variables and given/known data Use the McLaurin series for 1/(1+x) to show that I + N is invertible where N is a nilpotent matrix. 2. Relevant equations n/a 3. The attempt at a solution It has something to do with the inverse of 1+x is 1/(1+x), but i'm lost. I'm not sure where to start nor what exactly I need to do.
