Hey guys, I have a question for you... how would one go about solving an equation like this... or this... This came across my mind the other day. I was wondering how to solve that equation if the function is of t-1, instead of t. Obviously, if it was f(t), the solution would be Ce^t, but I was wondering if there is a way to find stuff for f(t-1). Is there any literature that would help lead meh into da right direction? Obviously my title doesn't do much justice, so I wanted to know if stuff like this has already been dun before! Thanks!
