# The Trig Library

The **Trig** library defines the standard trig functions, their inverse functions,
the hyperbolic trig functions and their inverse functions. It extends the commonly used commands
to include functionality to manipulate these objects.

The

**Trig**library defines:- The standard trig functions, the hyperbolic trig functions and the inverse functions for both groups.
- Functionality to move back and forth between degrees and radians.
To create an number in degrees, just type the number, then

**Space**, then "*degrees*" - the autocomplete popup will show the**Degrees**object with the number inside of it.The

**Convert**command can change back and forth between degrees and ratios of Pi for angles like 0, 90, etc. - Identities that relate trig functions. Many of these identities are accessible through
the
**Equivalence**command. Some are also accessible using commands like**Simplify**and**Expand**.
