I found this formula when I was studying neutron diffusion equation in Weston M. Stacey's book
Thanks in advance
cosβ=cosθx cosθ+sinθx sinθ cos(ψy−ψ)
Edited by moderator for clarity:
##\cos(\beta) = \cos(\theta_x)\cos(\theta) + \sin(\theta_x)\sin(\theta)\cos(\psi y - \psi)##
I have completed Calculus 1,2,3. I haven't yet completed differential equations.What other courses do I have to take to get started?
I know that there are difficult topics in reactor physics like neutron transport equation.So,it would be really helpful if you can give some guidelines so that I...
