CellMargins is an option for Cell that specifies the absolute margins in printer's points to leave around a cell.

Specularity[s] is a graphics directive which specifies that surfaces of 3D graphics objects which follow are to be taken to have specularity s. Specularity[s, n] uses ...

Implicit Runge–Kutta methods have a number of desirable properties. The Gauss–Legendre methods, for example, are self-adjoint, meaning that they provide the same solution ...

PointSize[d] is a graphics directive which specifies that points which follow are to be shown if possible as circular regions with diameter d. The diameter d is given as a ...

EquationTrekker[eqn, x, {t, t_min, t_max}] opens a graphical interface for specifying initial conditions and plotting the resulting numerical solution to the first or second ...

LogBarnesG[z] gives the logarithm of the Barnes G-function logG(z).

PrimePowerQ[expr] yields True if expr is a power of a prime number, and yields False otherwise.

This loads packages containing some test problems and utility functions. One of the first and simplest methods for solving initial value problems was proposed by Euler: ...

Through[p[f_1, f_2][x]] gives p[f_1[x], f_2[x]]. Through[expr, h] performs the transformation wherever h occurs in the head of expr.

General issues about the internal implementation of Mathematica are discussed in "The Internals of Mathematica". Given here are brief notes on particular features. These ...
