for A, B, C that sum to 180° (e.g. interior angles of a triangle):
sin²(A) =
sin²(B) + sin²(C) - 2cos(A)sin(B)sin(C)

S ⊆ {1, ..., N}
call S "mid" if, for every integer n, if n-1 and n+1 are elements of S, then n is in S.
#MathSky 🧮 #iTeachMath ♾️
example: if N=5, the set {2,3,4,5} is a mid subset.
⭐️ find a formula f(N) for the # of mid subsets of {1, ..., N} ⭐️
