\( \int x \sin \sqrt{x} \, dx \)

\( \int x \tan^2{x} \, dx \)

\( \int \frac{x \sin{x}}{\cos^3{x}} \, dx \)

\( \int \frac{x + \sin{x}}{\cos^2{x}} \, dx \)

•  Gặp: \( \int P(x) f(e^x) \, dx \)

•  Đặt  \( \begin{cases} u = P(x) \\ dv = f(e^x) \, dx \end{cases} \)

\( \int (x - 2) e^{2x} \, dx \)        (2006.D)

\( \int (x^2 + 2x - 1) e^{2x} \, dx \quad \text{(SGK chuẩn)}\)
