These are all functions which are of interest only to programmers, and
consequently we will not cover them here.
An introduction to programming on the hp 39g+ is covered in an earlier
chapter (see page 212) but those wanting more detail than is given there
must consult the manual. If you want more information then download aplets
from the internet and dismantle them.

These two groups of functions cover the Trigonometry functions, plus others,
which are less commonly used and which have consequently not been given
their own keys on the face of the calculator. Use them in the same way as
the normal SIN, COS and TAN functions.
COT, SEC etc
In the Trig. group of functions you will find:
Function Inverse function
COT (cotangent) ACOT (arc-cotangent)
CSC (cosec/cosecant) ACSC (arc-cosec)
SEC (secant) ASEC (arc-secant)
In the Hyperb. group of functions you will find (amongst other things):
Function Inverse function
SINH (hyperbolic sine or “shine”) ASINH (arc-hyp.sine)
COSH (hyperbolic cos or “cosh”) ACOSH (arc-hyp.cos)
TANH (hyperbolic tan) ATANH (arc-hyp.tan)
