Tìm $I=\int\limits_{}^{}\frac{x}{lnx}dx$
|
|
$$I=\int\limits_{0}^{1}\sqrt{\frac{x}{x^{3}+1}}dx.$$
Giúp mình với
$$I=\int\limits_{0}^{1}\sqrt{\frac{x}{x^{3}+1}}dx.$$
|

$I= \int\limits_{0}^{1} \frac{xe^{x}}{ (x+1)^{2}}dx$
Giúp em với!!
$I= \int\limits_{0}^{1} \frac{xe^{x}}{ (x+1)^{2}}dx$
|
|
$I= \int\limits_{0}^{\frac{\pi }{2}} \frac{\sin x-\cos x-\cos 2x}{\sin x+\cos x} dx$
Giúp mình tính tích phân...!!!
$I= \int\limits_{0}^{\frac{\pi }{2}} \frac{\sin x-\cos x-\cos 2x}{\sin x+\cos x} dx$

$\int\limits_{1}^{27} \frac{\sqrt{x}-2}{x+\sqrt[3]{x^2}}$
Tích phân
$\int\limits_{1}^{27} \frac{\sqrt{x}-2}{x+\sqrt[3]{x^2}}$
|
|
$\int\limits_{0}^{2}x\sqrt{\frac{x}{4-x}}dx$
tích phân nhé
$\int\limits_{0}^{2}x\sqrt{\frac{x}{4-x}}dx$
|
|
$\int\limits_{\frac{1}{2}}^{1}\sqrt{\frac{x}{x^{3}+1}} dx$
Giúp!!!
$\int\limits_{\frac{1}{2}}^{1}\sqrt{\frac{x}{x^{3}+1}} dx$
