Questions from a student :
  
 
When finding a basis, does it always have to be fully reduced? For example, if you have a basis [4 -2 6] does it need to be reduced to [2 -1 3] or is either answer acceptable? [[User:Jones947|Jones947]]

No, it doesn't need to be reduced. If  { [4 -2  6] } is a basis for some vector space <math>V</math>, then {  [2 -1  3] } is also a basis for <math>V</math> and vice versa. A basis for a vector space is not unique but a dimension of a vector space is unique.

Homework 2 collaboration area

Here is the Homework 2 collaboration area. Since HWK 2 is due the Wednesday after Labor Day, I won't have a chance to answer questions on Monday like usual. I will answer any and all questions here on the Rhea on Tuesday with help from Eun Young Park. - Steve Bell

Questions from a student :

When finding a basis, does it always have to be fully reduced? For example, if you have a basis [4 -2 6] does it need to be reduced to [2 -1 3] or is either answer acceptable? Jones947

Answer from Eun Young :

No, it doesn't need to be reduced. If { [4 -2 6] } is a basis for some vector space $ V $, then { [2 -1 3] } is also a basis for $ V $ and vice versa. A basis for a vector space is not unique but a dimension of a vector space is unique.
