Quizz vector spaces
--- Introduction ---

This module contains 11 training exercises on basic notions of
vector spaces.
Students may use them as a training tool for a better memorization of the lesson,
while teachers may put them into a work sheet with activated time limit, so that
proficiency can be tested.

### Two subsets

Let be a vector space. We have two subsets of ,
and
, having respectively and elements. Answer:

### Def dependence

Fill in:

### Def generation

Fill in:

### Dependence

Let
be a vector space,
a non-empty subset.

### Dimension and elements

Answer: Let
be a vector space,
a finite subset that . If ,
.

### Dim subspace by system

Let E be a sub-vector space of **R**^{} defined by a homogeneous linear system. This system is composed of equations, and the rank of the coefficient matrix of this system is equal to . What is the dimension of E?

### Generated subspace

Let
be a vector subspace of
generated by a subset
of elements. What can be said of the dimension of
?

dim(
) is
equal to
.

### Inclusion

Let
be a vector space,
,
two *distinct* finite subsets with
.

### Set
