1. The problem statement, all variables and given/known data I am trying to anti-differentiate (3t+2e^t)*[e^(-3t/2)] 2. Relevant equations 3. The attempt at a solution I have simplified this into several forms, including [3t(e^(-3t/2)+2e^(-t/2)] . This form may or may not be accurate, but I am pretty sure that the form given at the beginning of this post is accurate. But I cannot anti-differentiate either of them. A u-substitution maybe? I'm not sure. I cannot move past the problem I need to solve until I complete this step. Any help would be appreciated. Thank you for looking.
