very simple and easy to understand. thank you. But isn't cos = Adj / Hyp and not Hyp/Adj?

[@MidecaliEngineer]

I’m thankful you understand
Yes, cos = adj/hyp
In the triangle, I labeled my hyp (a) and my Adj was (height h). That’s where the misunderstanding came in.
a = length of unit cell, not adj
h= height not hyp
In my diagram and calculation
