Some Notes on Internal Implementation (Mathematica Tutorial)

General issues about the internal implementation of Mathematica are discussed in "The Internals of Mathematica". Given here are brief notes on particular features. These ...

N (Built-in Mathematica Symbol)

N[expr] gives the numerical value of expr. N[expr, n] attempts to give a result with n-digit precision.

Arbitrary-Precision Numbers (Mathematica Tutorial)

When you do calculations with arbitrary-precision numbers, Mathematica keeps track of precision at all points. In general, Mathematica tries to give you results which have ...

Cos (Built-in Mathematica Symbol)

Cos[z] gives the cosine of z.

Animate (Built-in Mathematica Symbol)

Animate[expr, {u, u_min, u_max}] generates an animation of expr in which u varies continuously from u_min to u_max. Animate[expr, {u, u_min, u_max, du}] takes u to vary in ...

Concurrency: Managing Parallel Processes (Parallel Package Tutorial)

A process is simply a Mathematica expression being evaluated. A processor is a parallel kernel that performs such evaluations. The command ParallelEvaluate discussed in the ...

AiryAiPrime (Built-in Mathematica Symbol)

AiryAiPrime[z] gives the derivative of the Airy function Ai^\[Prime] (z).

HypergeometricPFQ (Built-in Mathematica Symbol)

HypergeometricPFQ[{a_1, ..., a_p}, {b_1, ..., b_q}, z] is the generalized hypergeometric function \[Null]_p F_q (a; b; z).

Do Constrained Nonlinear Optimization (Mathematica How To)

An important subset of optimization problems is constrained nonlinear optimization, where the function is not linear and the parameter values are constrained to certain ...

OutputForm (Built-in Mathematica Symbol)

OutputForm[expr] prints as a two-dimensional representation of expr using only keyboard characters.
