integral of 12xe^{6x}

\int 12 x e^{6 x} d x

\frac{1}{3} (6 e^{6 x} x - e^{6 x}) + C

Solution steps

\int 12 x e^{6 x} d x

Take the constant out:

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

= 12 \cdot \int x e^{6 x} d x

Apply u-substitution

: \int \frac{e ^{u} u}{36} d u

= 12 \cdot \int \frac{e ^{u} u}{36} d u

Take the constant out:

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

= 12 \cdot \frac{1}{36} \cdot \int e^{u} u d u

Apply Integration By Parts

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

= 12 \cdot \frac{1}{36} (e^{u} u - \int e^{u} d u)

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

= 12 \cdot \frac{1}{36} (e^{u} u - e^{u})

Substitute back

u = 6 x

= 12 \cdot \frac{1}{36} (e^{6 x} \cdot 6 x - e^{6 x})

Simplify

12 \cdot \frac{1}{36} (e^{6 x} \cdot 6 x - e^{6 x}) : \frac{1}{3} (6 e^{6 x} x - e^{6 x})

= \frac{1}{3} (6 e^{6 x} x - e^{6 x})

Add a constant to the solution

= \frac{1}{3} (6 e^{6 x} x - e^{6 x}) + C

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

\frac{d y}{d x} = x y^{\frac{1}{2}}

\frac{d}{d x} (2 ln (2))

\int \frac{( x ^{2} - 25 ) ^{\frac{3}{2}}}{x ^{6}} d x

\frac{6 ( x ^{4} - 2 )}{x ^{3}}
