Basis problem

  1. Mar 8, 2008 #1
    Let B be the basis of R^2 consisting of the vectors :

    (4,1) and (1,3)

    and let R be the basis consisting of

    (-2,-3) and (-1,-2)

    Find a matrix P such that [x]_R = P [x]_B for all x in R^2

    *note: the vectors are columns, so in (4,1) the 4 is the top row and 1 is the bottom row.

    Really not sure how to start this problem. Please help.

    How would (4, 1) and (1, 3), the B basis vectors, be written in the R basis?

    The columns of matrix P will be those vectors.

    Alright, got it. I feel stupid now though.
