In 1 840, Belgian demographer Pierre Verhulst modified the Malthus model by proposing that the rate of growth dy/dt of the world's population y(t) should be proportional to ky - cy2 ; thus
dy/dt = ky - cy2.
Where both k and c are positive constants why do you think such a model may be feasible? What possible interpretations can you give for the tenncy2?
