X is an unknown vector

  1. Sep 17, 2006 #1
    X is an unknown vector satisfying the following relations involving the known vectors A and B and the scalar c,

    A x X = B

    A . X = c

    Express X in terms of A, B, c, and the magnitude of A

    I know that:

    A . X = |A| |X| cos(θ) = c


    |A x X| = |A| |X| sin(θ) = |B|

    but how do I get X by itself?

    You're going to have to break A, B and X into components and find out what the components of X are in terms of the components of A and B.
