How do I find what module to import for a given binding?

I’m trying to use sin but I have no idea what module I need to import to use it. I can find a reference to it in the Guile Reference Manual but that doesn’t mention the module sin is in. How do I figure this out?

In R7RS-small, sin is provided by the (scheme inexact) module. Refer to the spec for full details.

In Guile, sin is part of the default environment, implicitly via (guile) for “impure” modules. However, Hoot 0.4.1 doesn’t implement this module yet. Hoot 0.5.0 will have some amount of Guile compatibility in this regard.

Hope this helps!
