This simulation illustrates the convergence and the divergence of a function at infinity.

**Click** and **slide** the horizontal lines.

- To understand the notion of finite and infinite limits at infinity.
- To know how to state the convergence and/or divergence of a function at infinity.

Consider a function *f* defined on a subset of real numbers.

*f* admits a **finite limit ℓ at +∞** means that there is a real ε and real A such that the open interval containing ℓ, ] ℓ - ε, ℓ +…
