The integral of $2 \, dx$ is straightforward.

To find the integral, we treat $2$ as a constant:

$\int 2 \, dx = 2x + C$

Where $C$ is the constant of integration.

Would you like further details on integration or have any questions about the steps? Here's a list of related topics you might be interested in:

1. What is the meaning of the constant of integration $C$?
2. How do we integrate other simple constant functions like $3 \, dx$?
3. How do definite integrals differ from indefinite ones?
4. Can the integral of a constant function represent an area under a curve?
5. What are some common rules of integration?

Tip: Remember, the process of integration is essentially the reverse of differentiation. So, if you differentiate $2x$, you'd get $2$ back!
