Homework Help: Galactic transformation

  1. Jan 22, 2010 #1
    using the astronomical triangle of a source in equatorial and galactic coordinates ,prove that the transformations is true
    1) cos b cos(L-33 deg)=cos delta cos(alfa-282.25 deg)

    2) sin delta=cos b sin (L-33 deg) sin 62.6 deg +sin b cos 62.6 deg

    L,b galactic coordinates
    alfa,delta equatorial coordinates .

    2. Relevant equations
    L node =123-90=33 deg
    alfa node=12 h 49.0m+6h=18h 49.0m=282.25 deg

    3. The attempt at a solution
    using equatorial equations and cos and sin laws to determine the provment
