The technical guide introduces the Wolfram language and Mathematica software package for representing mathematical functions, and explains the commands for input, output, differentiation, limits, integration, probability, statistics, and data analysis. Separate chapters illustrate how to create interactive models with a single command, share Mathematica documents, visualize a list of numbers, customize graphics, import files and data, solve equations, construct matrices for linear algebra, extract part of a dataset, access curated data, and perform curve fitting.
