I Proof of solid angles

  1. Sep 30, 2017 #1
    I would like to ask you for hints to proof this:

    Code (Text):
    \int^4 pi \omega \omega \,d\omega =%fraction{4}{3} \pi
    where omega is vector.

    Do you have any hints for me? (Not seeing for solution, just hints).

    Please use our LaTeX code library to note formulas (https://www.physicsforums.com/help/latexhelp/)
    This is what I got from your code line, but I'm by no means sure that it is what you meant: ##\int^4_\pi \omega \omega \,d\omega =\frac{4}{3} \pi\,.## Also some explanations would be helpful. You originally posted it in a physics section, so what is physical here?
