Nested logical and piecewise functions can be expanded out much like nested arithmetic functions. You can do this using LogicalExpand and PiecewiseExpand. Expanding out ...

Extract[expr, list] extracts the part of expr at the position specified by list. Extract[expr, {list_1, list_2, ...}] extracts a list of parts of expr. Extract[expr, list, h] ...

You may wish to save your work in a format other than the default Mathematica notebook for sharing or publication. Mathematica has a very robust system for exporting your ...

ToBoxes[expr] generates boxes corresponding to the printed form of expr in StandardForm. ToBoxes[expr, form] gives the boxes corresponding to output in the specified form.

Mathematica lets you insert function templates that contain placeholders for the arguments of a function. You can do this directly from the keyboard or with several of ...

Mathematica has fundamental support for both explicit complex numbers and symbolic complex variables. All applicable mathematical functions support arbitrary-precision ...

The Part function allows you to access specific parts of Mathematica expressions. But particularly when your expressions have fairly uniform structure, it is often convenient ...

A foundational idea in Mathematica is that all expressions—whatever they may represent—ultimately have a uniform tree-like structure.

Long the standard for high-quality function and surface visualization, Mathematica incorporates a host of original numeric, symbolic, and geometric algorithms that automate ...

FileNameSplit["filename"] splits a file name into a list of parts.
