1. The problem statement, all variables and given/known data Find the limit of e(-t/2)((k/2)t+c) as t approaches infinity where k and c are constants 2. Relevant equations Not sure..? 3. The attempt at a solution Plugging in t = infinity gives me an indeterminate form, and multiple applications of L'hopital's rule have led me no where. Any suggestions? I can see graphically that it goes to 0, but I'm not sure how to show this analytically. I can see that if I expand it, the e(-t/2)c term goes to zero, but I'm not sure about the other term.
