Question: help with coordinate vector

I am trying to find the coordinate vector of v and w with respect to the basis T.

v= <1,5>  

w= <5,4>

T= [<1,1>|<2,3>]

 

I found this help page:

 

http://www.maplesoft.com/support/help/Maple/view.aspx?path=Task/VectorCoordinateVector

 

"Enter a vector in the vector space spanned by this basis"  -how do you know what to put in?

 

> V:=[<1,1>,<2,3>,<1,5>,<5,4>]

> A:= Matrix(LinearAlgebra[Basis]((A)))

> B:= <?,?>

> LinearAlgebra[LinearSolve]((A),(B))

Please Wait...
