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

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

\frac{1}{2} e^{- \frac{1}{x ^{2}}} + C

Solution steps

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

Apply u-substitution

: \int \frac{e ^{u}}{2} d u

= \int \frac{e ^{u}}{2} d u

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= \frac{1}{2} \cdot \int e^{u} d u

Use the common integral:

\int e^{u} d u = e^{u}

= \frac{1}{2} e^{u}

Substitute back

u = - \frac{1}{x ^{2}}

= \frac{1}{2} e^{- \frac{1}{x ^{2}}}

Add a constant to the solution

= \frac{1}{2} e^{- \frac{1}{x ^{2}}} + C

\int 2 + 3 x d x

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

\int x arcsin (\frac{1}{x}) d x

\int \frac{z}{e ^{7 z}} d z

\int \frac{x + 1}{x ^{2} + 2 x + 1} d x
