<b> BÀI TOÁN TÍCH PHÂN LUYỆN THI ĐẠI HỌC</b>
<b> </b>
1/ Cho hàm số : f(x)= x.sinx+x2<sub> . Tìm nguyên hàm của hàm số g(x)= x.cosx </sub>
biết rằng nguyên hàm này triệt tiêu khi x=k
2/Định m để hàm số: F(x) = mx3<sub>+(3m+2)x</sub>2 <sub>-4x+3 là một nguyên hàm của hàm số:</sub>
f(x) = 3x2<sub> +10x-4.</sub>
3/Tìm họ ngun hàm của hàm số: f(x)= cos3<sub>x.sin8x.</sub>
