*линейна обвивка*

The **span** of a set of vectors is the collection of all vectors which can be represented by some linear combination of the set.

In simple terms, if you choose *absolutely* any vector, anywhere in **span**

In the same way, we can get to any vector, anywhere in **span**

These facts are denoted by:

We cannot span

Given

anytwo linearly independent vectors, we can use them to define the entire real plane ()!
