1. The problem statement, all variables and given/known data Find an expression for e^A with the powerseries shown in the image linked 2. Relevant equations I know you have to use eigen values and eigen vectors and a diagonal matrix 3. The attempt at a solution What I did was just try to actually multiply out the infinite series given. I took it out to about 3 terms and said on my quiz that the rest will eventually go to zero so that this series will converge. However I got zero credit for this solution. I know how to get eigen values, but I just need help finding out how to get Q. Thanks.
