For functions involving angles (trigonometric functions, inverse trigonometric functions, etc.) we follow the convention that all angles are measured in radians. Thus, for instance, the angle of is measured as .

## Definition

This function, denoted , is defined as the composite of the cube function and the sine function. Explicitly, it is the map:

For brevity, we write or .
