* The expansion of vectors and Matrix equation*

- More vector notation. The notion of linear dependent ,what kind of
- transformation we needed for vectors and going from one basis to the other basis.
- Giving rule for the scalar product of two vectors.
- Explaining dual vector space, linear functions or a vector space.
- The concept of inverse elements
- Defining linear vectors and function and the value of the function
- in terms of basis .
- Natural map between vectors is given.
