Understanding Transformation Matrix Order for B and B'

Click For Summary
SUMMARY

The discussion clarifies that when defining the transformation matrix P from basis B to basis B', there is no requirement for the polynomials in B to be ordered by degree. Specifically, the example provided includes B = {1, 1+x, 3+4x+2x^2}, and it is emphasized that the transformation matrix's form depends on the chosen basis vectors and their order. The concept of ordering is not universally applicable across vector spaces, and users must specify the order of basis vectors when constructing the transformation matrix.

I was just wondering that when we take P, the transformation matrix from B to B', does B and B' have to be ordered from the highest thing?

What I mean is that I have B = 1, 1+x, 3+4x+2x^2 When I do the actual transformation, must I order it and do 2x^2+4x+3 first?

What are you talking about?
 
The highest "thing"? Is that some technical math term I don't know? I THINK you are talking about a vector space of polynomials with given polynomials as basis vectors. There is no requirement that the polynomials be in order of increasing or decreasing degree. In fact, for most vector spaces, there is no "natural" way of ordering vectors. The matrix form of a linear transformation WILL depend one the basis: both on the specific vectors and the order. So be sure that you specify how you are ordering the basis vectors.
