Dialogue: 0,0:00:00.67,0:00:02.79,Default,,0000,0000,0000,,Mình biết từ công thức đạo hàm tích
Dialogue: 0,0:00:02.79,0:00:06.51,Default,,0000,0000,0000,,là nếu mình có tích của hai hàm,
Dialogue: 0,0:00:06.51,0:00:10.20,Default,,0000,0000,0000,,gọi là f(x) và g(x) đi, và mình muốn tính
Dialogue: 0,0:00:10.20,0:00:15.52,Default,,0000,0000,0000,,đạo hàm của tích đó, thì nó sẽ
Dialogue: 0,0:00:15.52,0:00:16.98,Default,,0000,0000,0000,,bằng với đạo hàm
Dialogue: 0,0:00:16.98,0:00:20.28,Default,,0000,0000,0000,,của hàm thứ nhất, f'(x), nhân với
Dialogue: 0,0:00:20.28,0:00:27.95,Default,,0000,0000,0000,,hàm thứ hai, g(x), cộng với hàm thứ nhất
Dialogue: 0,0:00:27.95,0:00:30.83,Default,,0000,0000,0000,,(chính hàm số chứ không phải đạo hàm nhé)
Dialogue: 0,0:00:30.83,0:00:33.16,Default,,0000,0000,0000,,nhân với đạo hàm của hàm thứ hai.
Dialogue: 0,0:00:37.22,0:00:39.87,Default,,0000,0000,0000,,Vậy mình có hai số hạng, mỗi cái có đạo hàm
Dialogue: 0,0:00:39.87,0:00:42.37,Default,,0000,0000,0000,,một hàm thôi, và số hạng kia thì ngược lại.
Dialogue: 0,0:00:42.37,0:00:45.34,Default,,0000,0000,0000,,Đây là đạo hàm của f, không phải của g.
Dialogue: 0,0:00:45.34,0:00:47.52,Default,,0000,0000,0000,,Còn đây là đạo hàm của g, không phải của f.
Dialogue: 0,0:00:47.52,0:00:49.23,Default,,0000,0000,0000,,Mình ôn tập lại một chút về
Dialogue: 0,0:00:49.23,0:00:50.79,Default,,0000,0000,0000,,quy tắc đạo hàm tích như vậy.
Dialogue: 0,0:00:50.79,0:00:52.37,Default,,0000,0000,0000,,Rồi, bây giờ mình sẽ
Dialogue: 0,0:00:52.37,0:00:53.78,Default,,0000,0000,0000,,áp dụng quy tắc đạo hàm tích
Dialogue: 0,0:00:53.78,0:00:56.75,Default,,0000,0000,0000,,để tìm hiểu quy tắc đạo hàm thương.
Dialogue: 0,0:00:56.75,0:00:58.67,Default,,0000,0000,0000,,Mình không biết nghĩ sao
Dialogue: 0,0:00:58.67,0:01:01.09,Default,,0000,0000,0000,,Nó giúp mình làm một vài phép toán nhanh hơn,
Dialogue: 0,0:01:01.09,0:01:03.88,Default,,0000,0000,0000,,nhưng sự thật nó là từ quy tắc đạo hàm tích
Dialogue: 0,0:01:03.88,0:01:04.38,Default,,0000,0000,0000,,mà ra.
Dialogue: 0,0:01:04.38,0:01:06.32,Default,,0000,0000,0000,,Thật ra mình hay quên quy tắc đạo hàm thương lắm.
Dialogue: 0,0:01:06.32,0:01:09.23,Default,,0000,0000,0000,,Mình toàn tự tìm nó nhờ quy tắc đạo hàm tích thôi.
