#### 10.5.2.4 Additional Functions

Package: atrig1

  The `atrig1` package contains several additional simplification rules for inverse trigonometric functions. Together with rules already known to Maxima, the following angles are fully implemented: 0, \(\pi/6,\) \(\pi/4,\) \(\pi/3,\) and \(\pi/2.\)

  Corresponding angles in the other three quadrants are also available. Do `load("atrig1");` to use them.

Package: ntrig

  The `ntrig` package contains a set of simplification rules that are used to simplify trigonometric function whose arguments are of the form `f(n %pi/10)` where f is any of the functions `sin`, `cos`, `tan`, `csc`, `sec` and `cot`.
