A) Kích thước một quần thể y(t) tăng theo thời gian t mô hình bởi phương trình vi phân dy = k(M – y) với k, M là các hằng số dương và y(0) = y, (kích thước ban đầu quần thể là y,). dt Giải phương trình tìm y(t) và ước tính giá trị của y(t) sau khoảng thời gian t đủ lớn (tính theo các hằng số k, M,y,) b) Giải phương trình sai phân: y,+2 +2y,+1+2y, =24
