iatan in Elemntry:
is?(x, optan) => y
but only if -pi/2 < y < pi/2

These commands are too dangerous to execute here:
  \begin{axiom}
  atan(tan(3))
  )tr EF_;iatan
  atan(tan(3))
  )tr )off
  \end{axiom}

Try them at home at your own risk...

fricas
atan(cot(4))

\label{eq3}\arctan \left({\cot \left({4}\right)}\right)(3)
Type: Expression(Integer)
fricas
numeric %

\label{eq4}0.7123889803_8468985769(4)
Type: Float
fricas
atan(cot(4.0))

\label{eq5}0.7123889803_8468985769(5)
Type: Float

What about (temporary) document the domain of each function, for this package ?
