integral of (e^{1/(x^2)}+2x+ln(x))/(x^3)

\int \frac{e ^{\frac{1}{x ^{2}}} + 2 x + ln ( x )}{x ^{3}} d x

- \frac{1}{2} e^{\frac{1}{x ^{2}}} - \frac{2}{x} - \frac{ln ( x )}{2 x ^{2}} - \frac{1}{4 x ^{2}} + C

Solution steps

\int \frac{e ^{\frac{1}{x ^{2}}} + 2 x + ln ( x )}{x ^{3}} d x

Expand

\frac{e ^{\frac{1}{x ^{2}}} + 2 x + ln ( x )}{x ^{3}} : \frac{e ^{\frac{1}{x ^{2}}}}{x ^{3}} + \frac{2}{x ^{2}} + \frac{ln ( x )}{x ^{3}}

= \int \frac{e ^{\frac{1}{x ^{2}}}}{x ^{3}} + \frac{2}{x ^{2}} + \frac{ln ( x )}{x ^{3}} d x

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int \frac{e ^{\frac{1}{x ^{2}}}}{x ^{3}} d x + \int \frac{2}{x ^{2}} d x + \int \frac{ln ( x )}{x ^{3}} d x

\int \frac{e ^{\frac{1}{x ^{2}}}}{x ^{3}} d x = - \frac{1}{2} e^{\frac{1}{x ^{2}}}

\int \frac{2}{x ^{2}} d x = - \frac{2}{x}

\int \frac{ln ( x )}{x ^{3}} d x = - \frac{ln ( x )}{2 x ^{2}} - \frac{1}{4 x ^{2}}

= - \frac{1}{2} e^{\frac{1}{x ^{2}}} - \frac{2}{x} - \frac{ln ( x )}{2 x ^{2}} - \frac{1}{4 x ^{2}}

Add a constant to the solution

= - \frac{1}{2} e^{\frac{1}{x ^{2}}} - \frac{2}{x} - \frac{ln ( x )}{2 x ^{2}} - \frac{1}{4 x ^{2}} + C

\int \frac{1}{cos ( x ) + 2} d x

\int \frac{3}{( 1 - 2 x ) ^{2}} d x

\int (\frac{1}{4} x^{3} + 3 x^{2} - \frac{3}{4} x + 4) d x

\int e^{8 x} sin (e^{8 x}) d x

\int \frac{7 x}{x ^{4} + 1} d x
