Basis (linear algebra) facts for kids
- One can get any vector in the vector space by multiplying each of the basis vectors by different numbers, and then adding them up.
- If any vector is removed from the basis, the property above is no longer satisfied.
The dimension of a given vector space is the number of elements of the basis.
If is the vector space then:
is a basis of .
It's easy to see that for any element of it can be represented as a combination of the above basis. Let be any element of and let .
Since and are elements of then they can be written as and so on.
Then the combination equals the element .
This shows that the set is a basis of .
