1. The problem statement, all variables and given/known data Find the singular points for: x' = ax - bxy y' = bxy - cy 2. Relevant equations 3. The attempt at a solution ax - bxy = 0 bxy - cy = 0 implies x = 0 or y = a/b y = 0 or x = c/b the the critical points are (o,o) or (c/b, a/b) why is (0, a/b) and (c/b, 0) NOT a critical point??
