A population y(t) of fishes in a lake behaves according to the logistic law with a rate of growth per minute a = 0.003 and a limiting growth rate per minute b = 0.001. Moreover, 0.002 are leaving the lake every minute.
1.1
Write the dierential equation which is satisfied by y(t). Solve it when the initial population is of one million fishes.
1.2
Compute
1.3
