Arccos
f(x) = arccos(x)
Overview
Arccos is the inverse of cos, restricted to [0, π]. It gives the angle in the upper half.
Domain
[-1, 1]
Range
[0, π]
Symmetry
Neither
Key Properties
1
Domain: [-1, 1]
2
Range: [0, π]
3
Neither even nor odd
4
arcsin(x) + arccos(x) = π/2
Key Insight
arcsin(x) + arccos(x) = π/2 for all x in [-1,1]. They're complementary angles!
