UnderoverscriptBox[x, y, z] is the low-level box representation for x_y^z in notebook expressions.
Unique
(Built-in Mathematica Symbol) Unique[] generates a new symbol, whose name is of the form $nnn. Unique[x] generates a new symbol, with a name of the form x$nnn. Unique[{x, y, ...}] generates a list of new ...
$BaseDirectory gives the base directory in which systemwide files to be loaded by Mathematica are conventionally placed.
$BatchInput is True if input in the current session is being fed directly to the Mathematica kernel in batch mode.
$ModuleNumber gives the current serial number to be used for local variables that are created.
$UserBaseDirectory gives the base directory in which user-specific files to be loaded by Mathematica are conventionally placed.
Basic plotting functions. This plots a graph of sin(x) as a function of x from 0 to 2π. You can plot functions that have singularities. Mathematica will try to choose ...
We first encountered lists in "Making Lists of Objects" as a way of collecting numbers together. Here, we shall see many different ways to use lists. You will find that lists ...
You can define the derivative in Mathematica of a function f of one argument simply by an assignment like f'[x_]=fp[x]. This defines the derivative of f(x) to be fp(x). In ...
Differentiating a known function gives an explicit result. Differentiating an unknown function f gives a result in terms of f'. Mathematica applies the chain rule for ...
