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 $90\,^{\circ }$ is measured as $\pi /2$.

Definition

This function is defined as the composite of the sine function and the reciprocal function. In other words, it is the function:

$x\mapsto \sin(1/x),\qquad x\neq 0$
