Advanced Linear Algebra

  1. Feb 11, 2012 #1
    I found the final answer posted online, but my work doesn't match up.

    v1 = 3t
    v2 = 5t1/2 - 6t

    Orthonormalized:

    [itex]
    v_1 = \sqrt{3}t [/itex] is correct.

    [itex]
    v_2 = \frac{1}{\sqrt{61}}(5t^{1/2} - 6t)[/itex] does not match.

    Furthermore, my part (b) is wrong, too. I know my methods are correct. I don't understand why the answers aren't matching.

    I realized some of my arithmetic is wrong/incomplete towards the end on (b). It's even worse now.

    Well, for one thing ##v_1## isn't ##3t##. It is ##t\sqrt 3 ##.

    Okay, yeah. I see what I wrote down that wasn't exactly right. Let me see if I didn't anything else wrong for the second orthogonal vector.

    I found the problem. Thanks!
