Question
Evaluate the indefinite integral. Illustrate, and check that your answer is reasonable, by graphing both the function and its antiderivative $($ take $C=0)$.$$\int x e^{-2 x} d x$$
Step 1
The formula for integration by parts is $\int u dv = uv - \int v du$. We need to choose our u and dv. Let's choose $u = x$ and $dv = e^{-2x} dx$. Show more…
