Hi, could someone explain to me the concept and calculation of Solid Angle? I don't think we've actually covered it in our Vector Calculus lectures and I have a question to do on it!!! Tried searching on the web, but not much information and I really don't understand it.(adsbygoogle = window.adsbygoogle || []).push({});

Also, my question is:

"Calculate the Solid Angle of a cone of half-angle 'alpha'".

What is the half-angle in a cone?
