integral of x^5e^{-x^6}

\int x^{5} e^{- x^{6}} d x

- \frac{1}{6} e^{- x^{6}} + C

Solution steps

\int x^{5} e^{- x^{6}} d x

Apply u-substitution

: \int - \frac{e ^{u}}{6} d u

= \int - \frac{e ^{u}}{6} d u

Take the constant out:

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

= - \frac{1}{6} \cdot \int e^{u} d u

Use the common integral:

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

= - \frac{1}{6} e^{u}

Substitute back

u = - x^{6}

= - \frac{1}{6} e^{- x^{6}}

Add a constant to the solution

= - \frac{1}{6} e^{- x^{6}} + C

x + y (\frac{d y}{d x}) = 0

\int (x x + 6) d x

\int 7 cos (θ) cos^{5} (sin (θ)) d θ

arccos (7 x^{3})

\frac{\partial}{\partial x} (2 y e^{x^{2} + y^{2}})
