A tag is a keyword or label that categorizes your question with other, similar questions. Using the right tags makes it easier for others to find and answer your question.
Questions specific to the Wolfram Cloud products.
Question relating numerical representations, operations and methods, including approximate results instead of exact symbolic results.
Questions relating to the importing, exporting, and extraction of data from PDF files
Questions about Mathematica's procedural programming paradigm.
The Kernel is the back-end application thread that does the actual evaluation of all non-graphical expressions. It can be accessed directly through the console but is more commonly working behind the…
For questions about Wolfram Language Scripts (formerly known as Mathematica Script), or running the kernel without direct user interaction.
Styles define how Mathematica notebooks, cells and expressions are formatted, displayed, evaluated and interacted with.
Questions about transformation rules in Mathematica--constructs that let you set, or programmatically modify, local values for expressions.
Mathematica symbols are the ultimate atoms of symbolic data. Every symbol has a unique name, exists in a certain Mathematica context or namespace, and can have a variety of types of values and attribu…
For questions regarding the underlying implementation of built-in functions.
Tag for the usage of RSolve, RecurrenceTable, DifferenceRoot, and other functions related to difference equations.
Questions which deal with or solve for functions expressed in integral form, i.e., one or more unknown functions that appear under an integral sign.
Questions on the use or manipulation of Mathematica variables (i.e. names associated with a changeable value). Use [variable-definitions] or [assignment] for questions on variable context localization…
Questions on sequences where adjacent samples are time-correlated, making the data suitable for modeling the behavior of the sampled system.
Questions about any kind of interaction with TeX, LaTeX, and friends, including transferring text/code to/from TeX, using Mathematica graphics in LaTeX documents etc.
Questions about the form and content of output returned by Mathematica for a given input or function application. This can include specific differences produced by older versions of Mathematica.
Questions on the construction and manipulation of sparse arrays in Mathematica, with functions like SparseArray and Band.
Questions on undocumented functionality of Mathematica. Note that such functions might be subject to change without notice in future versions.
Questions about using, converting, or interpreting units of measurement in Mathematica.
Questions on dealing with vector calculus functions of Mathematica such as Grad, Div, Curl, Laplacian and their representations in various coordinate systems.
For questions relating to assignments to symbols, patterns, or expressions.
Questions relating to Mathematica's sound and audio functionality, including Play, Sound, Audio and Speak.
Questions on the application of Mathematica to geography, including the use of the CountryData and CityData functions. Not to be confused with geodesy.
Simulation is the imitation of the operation of a real-world process or system over time.
Abstract manipulation of symbols. Transforming an algebraic expression into the desired form.
For questions related to chemical concepts such as solving equations related to reaction kinetics, graphically visualizing molecules, and using the chemistry-related curated data sets.
Homework questions are welcome, as long as they are asked honestly, explain the problem, and show sufficient effort. Please do not use this as the only tag for a question. Please do not add this tag t…
Questions on applying common nonlinear scalings to functions or data--useful for making sense of data which varies over a large range.
For interacting with the Mathematica front-end using the keyboard: shortcut keys, KeyEvents, keyboard navigation, etc.
For questions about the functionality related to permutations in Mathematica.
Questions about using or composing operators--functional mappings from one state or vector space to another.
Questions about using Mathematica for accessing web sites and using such functions as URLFetch and URLSave.
MathLink is a suite of Mathematica functions that implement a protocol for the communication/interfacing of Mathematica with external programs.
Tag to mark questions that are specific to Windows platforms. This includes questions about the windows file system, installation issues, COM interfacing, running external programs etc.
Tag used to indicate that a question presents code or methods that may lead to a crash. Useful as a warning to prevent other users from experiencing the same without having saved their work.
