Difference between vector basis and bases?

In summary, a vector basis is a set of linearly independent vectors used to represent any vector in a vector space, while a basis is a set of linearly independent vectors used to span a vector space. A vector basis can also be a basis, but not all bases are vector bases. Vector bases and bases are important concepts in linear algebra used to represent and manipulate vectors and linear transformations. Having a vector basis in a vector space allows for easier calculations and understanding of its properties. To determine if a set of vectors form a vector basis, they must be linearly independent and span the vector space.

I am not sure I understand you correctly, "bases" is the plural of "basis".
 
  • #3
A given vector space can have many bases. For example, R2 has the standard basis {(1, 0), (0, 1)}, but the following set is also a basis for R2--{(1, 1), (1, -1)}. In fact, any two vectors in R2 that aren't scalar multiples of each other would serve as a basis for R2.
 

Related to Difference between vector basis and bases?

1. What is the difference between a vector basis and a basis?

A vector basis is a set of linearly independent vectors that can be used to represent any vector in a vector space. A basis, on the other hand, is a set of linearly independent vectors that can be used to span a vector space. In other words, a vector basis is a special type of basis that consists of vectors, while a basis can consist of any type of elements.

2. Can a vector basis and a basis be the same?

Yes, a vector basis can also be a basis, but not all bases are vector bases. For example, in a two-dimensional vector space, the vectors (1,0) and (0,1) form a vector basis as well as a basis for the space.

3. How are vector bases and bases used in linear algebra?

Vector bases and bases are fundamental concepts in linear algebra that are used to represent and manipulate vectors and linear transformations. They are used to solve systems of linear equations, find solutions to linear transformations, and study the properties of vector spaces.

4. What is the significance of having a vector basis in a vector space?

A vector basis is important because it allows us to express any vector in a vector space as a linear combination of a set of basis vectors. This makes it easier to represent and manipulate vectors and perform calculations in a vector space. Additionally, having a vector basis also helps us to understand the properties and structure of a vector space.

5. How do you determine if a set of vectors form a vector basis?

To determine if a set of vectors form a vector basis, we need to check if the vectors are linearly independent and span the vector space. This can be done by solving a system of linear equations or by performing matrix operations on the vectors. If the vectors are linearly independent and span the vector space, then they form a vector basis.
