Cho tích phân \(I = \int\limits_a^b {f\left( x \right).g'\left( x \right){\rm{d}}x} ,\) nếu đặt \(\left\{ \matrix{u = f\left( x \right) \hfill \cr {\rm{d}}v = g'\left( x \right){\rm{d}}x \hfill \cr} \right.\) thì
A.\(I = \left. {f\left( x \right).g'\left( x \right)} \right|_a^b - \int\limits_a^b {f'\left( x \right).g\left( x \right){\rm{d}}x} .\)
B.\(I = \left. {f\left( x \right).g\left( x \right)} \right|_a^b - \int\limits_a^b {f\left( x \right).g\left( x \right){\rm{d}}x} .\)
C.\(I = \left. {f\left( x \right).g\left( x \right)} \right|_a^b - \int\limits_a^b {f'\left( x \right).g\left( x \right){\rm{d}}x} .\)
D.\(I = \left. {f\left( x \right).g'\left( x \right)} \right|_a^b - \int\limits_a^b {f\left( x \right).g'\left( x \right){\rm{d}}x} .\)
A.\(I = \left. {f\left( x \right).g'\left( x \right)} \right|_a^b - \int\limits_a^b {f'\left( x \right).g\left( x \right){\rm{d}}x} .\)
B.\(I = \left. {f\left( x \right).g\left( x \right)} \right|_a^b - \int\limits_a^b {f\left( x \right).g\left( x \right){\rm{d}}x} .\)
