$e^w\left(-1+w\right)+C_0$

## Step-by-step explanation

Problem to solve:

$\int w e^wdw$
1

Use the integration by parts theorem to calculate the integral $\int we^wdw$, using the following formula

$\displaystyle\int u\cdot dv=u\cdot v-\int v \cdot du$
2

First, identify $u$ and calculate $du$

$\begin{matrix}\displaystyle{u=w}\\ \displaystyle{du=dw}\end{matrix}$

$e^w\left(-1+w\right)+C_0$
$\int w e^wdw$
