\(\int_{-1}^0\)\(\dfrac{4x+4}{\left(x^2-4x+3\right)^2}dx\)
\(\int_0^1\)\(\dfrac{2x^3-3x^2+x-4}{x^2+2x+1}dx\)
\(\int_{-1}^0\) \(\dfrac{x^2-4x+4}{x^2-1}dx\)
a) \(\int_{\dfrac{\pi}{8}}^{\dfrac{2\pi}{8}}\)\(\dfrac{dx}{sin^2xcos^2x}\)
b) \(\int_{\dfrac{\pi}{6}}^{\dfrac{\pi}{3}}\)\(\dfrac{cos2xdx}{sin^2xcos^2x}\)
c) \(\int_0^{\dfrac{\pi}{3}}\)\(\dfrac{cos3x}{cosx}\)dx
\(\int_2^5\) \(\dfrac{-x^4-3x^2+4}{x^2-1}dx\)
Tính tích phân: \(\int_{\dfrac{1}{8}}^{\dfrac{1}{3}}\dfrac{1}{x}\sqrt{\dfrac{1+x}{x}}dx\)
\(\int\dfrac{x^2-3}{x\left(x^4+3x^2+2\right)}dx\)
Anh Lâm ơi giúp em với, nên đặt gì làm ẩn bây giờ ạ?
help me
tính
Câu 1: A=\(\int\dfrac{2SINX+COSX}{3SINX+2COSX}DX\)
Câu 2: \(I=\int\dfrac{X^3}{X^4+3X^2+2}\)
\(\int_{\dfrac{\pi}{4}}^{\dfrac{\pi}{3}}\)\(\dfrac{cos2x}{sin^2x}dx\)
