Câu hỏi: Cho tích phân \(I = \int\limits_a^b {f\left( x \right).g'\left( x \right){\text{d}}x} ,\) nếu đặt 

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. \(I = \left. {f\left( x \right).g'\left( x \right)} \right|_a^b - \int\limits_a^b {f\left( x \right).g'\left( x \right){\rm{d}}x} .\)
