Factoring a quadratic polynomial in one variable is straightforward. But Mathematica routinely factors degree-100 polynomials in 3 variables—by making use of a tower of ...

SDTS GIS format. Geographic information standard used by the U.S. Geological Survey. Used for archiving and exchanging maps and map data. SDTS is an acronym for Spatial Data ...

Not only can Mathematica perform very complicated data analysis, it can also display these results in a formatted, easy-to-read display that can be used in other documents or ...

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

Mathematica 6.0 represented a major new level in Mathematica's distinguished twenty-year history of broad cutting-edge algorithm development. Mathematica's unified ...

GeoGridPosition[{x, y, z}, projection] represents a point {x, y, z} in a planimetric cartographic grid using the specified projection.

LogicalExpand[expr] expands out logical combinations of equations, inequalities, and other functions.

The function NDSolve discussed in "Numerical Differential Equations" allows you to find numerical solutions to differential equations. NDSolve handles both single ...

Expressions are the main type of data in Mathematica. Expressions can be written in the form h[e_1,e_2,…]. The object h is known generically as the head of the expression. ...

Mathematica creates a new symbol when you first enter a particular name. Sometimes it is useful to "intercept" the process of creating a new symbol. Mathematica provides ...
