LegendreP[n, x] gives the Legendre polynomial P_n (x). LegendreP[n, m, x] gives the associated Legendre polynomial P_n^m(x).
Mod
(Built-in Mathematica Symbol) Mod[m, n] gives the remainder on division of m by n. Mod[m, n, d] uses an offset d.
Rationalize[x] converts an approximate number x to a nearby rational with small denominator. Rationalize[x, dx] yields the rational number with smallest denominator that lies ...
Rectangle[{x_min, y_min}, {x_max, y_max}] is a two-dimensional graphics primitive that represents a filled rectangle, oriented parallel to the axes. Rectangle[{x_min, y_min}] ...
RegionPlot[pred, {x, x_min, x_max}, {y, y_min, y_max}] makes a plot showing the region in which pred is True.
RootReduce[expr] attempts to reduce expr to a single Root object.
Rotate
(Built-in Mathematica Symbol) Rotate[g, \[Theta]] represents 2D graphics primitives or any other objects g rotated counterclockwise by \[Theta] radians about the center of their bounding box. Rotate[g, ...
RuntimeOptions is an option for Compile that specifies runtime settings for the compiled function it creates.
SolveAlways[eqns, vars] gives the values of parameters that make the equations eqns valid for all values of the variables vars.
SphericalPlot3D[r, \[Theta], \[Phi]] generates a 3D plot with a spherical radius r as a function of spherical coordinates \[Theta] and \[Phi].SphericalPlot3D[r, {\[Theta], ...
