I'm in a macroeconomics course that deals with calculus as well and it's not one of my strengths. I'm doing my homework and I was hoping for some help with it (I'm lost on all of the questions since the Solow Model confuses me a bit. The first question gives Kt+1 = sF (Kt, AtLt) + (1 − δ)Kt and asks to find the fundmamental equation of the Solow Model in discrete time with both population growth and technological growth (n,g). Hoping I can get some help with how to do these questions!
