CriticalSection (Built-in Mathematica Symbol)

CriticalSection[{var_1, var_2, ...}, expr] locks the variables var_i with respect to parallel computation, evaluates expr, then releases the var_i.

Deinitialization (Built-in Mathematica Symbol)

Deinitialization is an option for Dynamic, DynamicModule, Manipulate, and related constructs that specifies an expression to be evaluated when the construct can no longer be ...

TrueQ (Built-in Mathematica Symbol)

TrueQ[expr] yields True if expr is True, and yields False otherwise.

SetDelayed (Built-in Mathematica Symbol)

lhs := rhs assigns rhs to be the delayed value of lhs. rhs is maintained in an unevaluated form. When lhs appears, it is replaced by rhs, evaluated afresh each time.

Namespace Management (Mathematica Guide)

Mathematica supports dynamic hierarchical namespace management, fully integrated into the Mathematica language. Mathematica's symbolic programming paradigm allows a unique ...

Tokens Related to the Format Menu (Mathematica Guide)

Mathematica allows any front end command to be executed programmatically from within the kernel by sending an appropriate front end token. There are tokens for all standard ...

NotebookDelete (Built-in Mathematica Symbol)

NotebookDelete[notebook] deletes the current selection in the notebook corresponding to the specified notebook object. NotebookDelete[] deletes the current selection in the ...

Exact Linear Second-Order Equations (Mathematica Tutorial)

A linear second-order ordinary differential equation is said to be exact if An exact linear second-order ODE is solved by reduction to a linear first-order ODE.
