# represents the first argument supplied to a pure function. # n represents the n\[Null]\[Null]^th argument.

Exact symbolic results are usually very desirable when they can be found. In many calculations, however, it is not possible to get symbolic results. In such cases, you must ...

Like everything else in Mathematica the textual forms of expressions can themselves be represented as expressions. Textual forms that consist of one-dimensional sequences of ...

There are often many different ways to write the same algebraic expression. As one example, the expression (1+x)^2 can be written as 1+2x+x^2. Mathematica provides a large ...

SampledSoundList[{a_1, a_2, ...}, r] is a sound primitive that represents a sound whose amplitude has levels a_i sampled r times a second.

Mathematica can import and export hundreds of data formats and subformats. These "How tos" give step-by-step instructions for tasks related to importing and exporting some of ...

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 ...

To get a radical, press the Control key and the 2 key at the same time. Press Ctrl+2 or Ctrl+@. Type the radicand inside the placeholder (which is already selected).

Mathematica can represent bit vectors of arbitrary length as integers, and uses highly optimized algorithms—including several original to Wolfram Research—to perform bitwise ...
