BetaRegularized[z, a, b] gives the regularized incomplete beta function I_z (a, b).
EulerPhi[n] gives the Euler totient function \[Phi](n).
GammaRegularized[a, z] is the regularized incomplete gamma function Q(a, z).
PolyLog
(Built-in Mathematica Symbol) PolyLog[n, z] gives the polylogarithm function Li_n (z).PolyLog[n, p, z] gives the Nielsen generalized polylogarithm function S n, p (z).
Table
(Mathematica Import/Export Format) Generic tabular data. Stores numerical and textual information, formatted as a table. Supports user-defined field and record separators, field delimiters, currency tokens, ...
Thread
(Built-in Mathematica Symbol) Thread[f[args]] "threads" f over any lists that appear in args. Thread[f[args], h] threads f over any objects with head h that appear in args. Thread[f[args], h, n] threads f ...
Assuming[assum, expr] evaluates expr with assum appended to $Assumptions, so that assum is included in the default assumptions used by functions such as Refine, Simplify, and ...
Collect
(Built-in Mathematica Symbol) Collect[expr, x] collects together terms involving the same powers of objects matching x. Collect[expr, {x_1, x_2, ...}] collects together terms that involve the same powers ...
ComplexExpand[expr] expands expr assuming that all variables are real. ComplexExpand[expr, {x_1, x_2, ...}] expands expr assuming that variables matching any of the x_i are ...
ConfidenceLevel is an option for LinearModelFit and other fitting functions that specifies the confidence level to use in generating parameter and prediction intervals.
