HI Professor Shafrir, I have chosen you because I like your pedagogic method for explaining each steps.
In the following attached problem, the professor gives us the solution but didn't explain the way.
So I don't need the solution, I have it. All I need to understand is how to get from step 1 (the Taylor series) to step 2 (The last step) with a matrixe e^A with entries consisting in exponentials e, for questions (a) and question (b) only.
Thank you, Professor.© BrainMass Inc. brainmass.com March 5, 2021, 12:29 am ad1c9bdddf
