ExtendedGCD[n_1, n_2, ...] gives the extended greatest common divisor of the integers n_i.
RowBox
(Built-in Mathematica Symbol) RowBox[{box_1, box_2, ...}] is a low-level box construct that represents a row of boxes or strings in a notebook expression.
SpheroidalJoiningFactor[n, m, \[Gamma]] gives the spheroidal joining factor with degree n and order m.
SpheroidalS2Prime[n, m, \[Gamma], z] gives the derivative with respect to z of the radial spheroidal function S_n^m, (2)(\[Gamma], z) of the second kind.
SubscriptBox[x, y] is the low-level box representation for x_y in notebook expressions.

Update
(Built-in Mathematica Symbol) Update[symbol] tells Mathematica that hidden changes have been made which could affect values associated with a symbol. Update[] specifies that the value of any symbol could ...
When you create or use Mathematica packages, you will often want to refer to files in a system-independent way. You can use contexts to do this. The basic idea is that on ...
