1. The problem statement, all variables and given/known data I have two equations. 1. b(N) = rN^k 2. bN° = Y - X - C How can I find an expression for N°/N 2. Relevant equations 3. The attempt at a solution I am a little lost here since I dont know much about the properties of differential equations. So my attempts at solution has been to take the derivative of the first equation and call it N°, which I dont know if I am alloved to do. Then insert it into the second equation and solve it for N. It doesent seem to be right.
