For a pancake distribution of sin(a), where a = 0, determine the ratio of the average flux for e > 45 to the omnidirectional flux. What I need from here is:Directional Flux, Omnidirectional Flux,Directional Solid Angle, Omnidirectional Solid Angle. Then: Find the Flux per Solid Angle (For both the directional and omnidirectional cases) And find the ratio of those two
