When you have numerical data, it is often convenient to find a simple formula that approximates it. For example, you can try to "fit" a line or curve through the points in ...

Even simple-looking limits are sometimes quite complicated to compute. Mathematica provides functionality to evaluate several kinds of limits.

$ReleaseNumber is an integer which gives the current Mathematica kernel release number, and increases in successive releases.

Message[symbol::tag] prints the message symbol::tag unless it has been switched off. Message[symbol::tag, e_1, e_2, ...] prints a message, inserting the values of the e_i as ...

AlgebraicIntegerQ[a] yields True if a is an algebraic integer, and yields False otherwise.

ToExpression[input] gives the expression obtained by interpreting strings or boxes as Mathematica input. ToExpression[input, form] uses interpretation rules corresponding to ...

DialogInput[expr] interactively puts up expr as a dialog notebook, waits until a DialogReturn[e] is evaluated from within it, and then returns the result e. DialogInput[{x = ...

$SyntaxHandler is a global variable which, if set, is applied to any input string that is found to contain a syntax error.

MatrixExp[m] gives the matrix exponential of m. MatrixExp[m, v] gives the matrix exponential of m applied to the vector v.

Mathematica's Cluster Integration provides a uniquely seamless interface to cluster management systems. With Cluster Integration you can launch and manage jobs running ...
