Given a coordinate (x, y) on the circle, the x-value represents the cosine of the angle. 5), which is π/3 radians.

Key Characteristics Domain: [-1, 1] Range: [0, π] radians End Behavior: f(-1) = π and f(1) = 0 Symmetry: The function is neither even nor odd Relationship with the Unit Circle On the unit circle, the inverse cosine directly corresponds to the angle measurement. Arccos(x) calculates the specific angle in the upper half of the circle (0 to π radians) that produces that x-coordinate.
This ensures a unique output for every valid input. This geometric interpretation is vital for solving trigonometric equations.
