InputForm[expr] prints as a version of expr suitable for input to Mathematica.
QPolyGamma[z, q] gives the q-digamma function \[Psi]_q (z).QPolyGamma[n, z, q] gives the n\[Null]^th derivative of the q-digamma function \[Psi]_q^(n)(z).
Lighting is an option for Graphics3D and related functions that specifies what simulated lighting to use in coloring 3D surfaces.
GraphicsRow[{g_1, g_2, ...}] generates a graphic in which the g_i are laid out in a row.GraphicsRow[list, spacing] leaves the specified spacing between successive elements.
Sum
(Built-in Mathematica Symbol) Sum[f, {i, i_max}] evaluates the sum \[Sum]i = 1 i_max f. Sum[f, {i, i_min, i_max}] starts with i = i_min. Sum[f, {i, i_min, i_max, di}] uses steps d i. Sum[f, {i, {i_1, i_2, ...
MultivariateTDistribution[\[CapitalSigma], \[Nu]] represents the multivariate Student t distribution with scale matrix \[CapitalSigma] and degrees of freedom parameter ...
StabilityMarginsStyle is an option to frequency response plots such as BodePlot, NyquistPlot, and NicholsPlot that specifies the styles in which the gain and phase margins ...
NSolve
(Built-in Mathematica Symbol) NSolve[expr, vars] attempts to find numerical approximations to the solutions of the system expr of equations or inequalities for the variables vars. NSolve[expr, vars, ...
NSeries
(Numerical Calculus Package Symbol) NSeries[f, {x, x_0, n}] gives a numerical approximation to the series expansion of f about the point x = x_0 including the terms (x - x_0) -n through (x - x_0) n.
