3D Vectors

  1. Sep 20, 2007 #1
    1. The problem statement, all variables and given/known data
    http://www.tunerspec.ca/school/3dvector.jpg [Broken]

    2. Relevant equations
    [tex]c^{2} = a^{2} + b^{2} - 2ab \times cos \alpha[/tex]
    [tex]\frac{sin a}{a}[/tex] = [tex]\frac{sin b}{b}[/tex]

    3. The attempt at a solution
    I really don't know where to get started... I don't want someone to just do it for me - just a little help would be nice. :)
