Limit[expr,x->x_0] tells you what the value of expr is when x tends to x_0. When this value is infinite, it is often useful instead to know the residue of expr when x equals ...

Mathematica provides a convenient collection of platform-independent functions for manipulating names of files and directories. These functions can also be used to assemble ...

Just as the equation x^2+3x==2 asserts that x^2+3x is equal to 2, so also the inequality x^2+3x>2 asserts that x^2+3x is greater than 2. In Mathematica, Reduce works not only ...

Mathematica includes functions for performing a variety of specific algebraic transformations. Some are algorithmically straightforward; others include highly sophisticated ...

Numerical sums, products and integrals. Here is a numerical approximation to ∑_(i=1)^∞((1)/(i^3)). NIntegrate can handle singularities in the integration region.

Beyond using a keyboard or mouse, you can control Mathematica with a joystick, gamepad, 3D mouse, or any device that follows the industry-standard human interface device ...

RuntimeAttributes is an option for Compile that specifies attributes for the compiled function it creates.

AddToClassPath[path_1, path_2, ...] adds the specified full paths to directories and jar or zip files to the J/Link class search path.

Stack[] shows the current evaluation stack, giving a list of the tags associated with evaluations that are currently being done. Stack[pattern] gives a list of expressions ...
