Entering Formulas (Mathematica Tutorial)

Special forms for some common symbols. This is equivalent to Sin[60Degree]. Here is the long form of the input.

Termination Conditions (Mathematica Tutorial)

Mathematically, sufficient conditions for a local minimum of a smooth function are quite straightforward: x^* is a local minimum if ∇f(x^*)=0 and the Hessian ∇^2f(x^*) is ...

Integrals That Can and Cannot Be Done (Mathematica Tutorial)

Evaluating integrals is much more difficult than evaluating derivatives. For derivatives, there is a systematic procedure based on the chain rule that effectively allows any ...

GUIResolve (GUIKit Package Symbol)

GUIResolve[src] resolves an interface definition to its top-level completely loaded widget and enclosing widgets.GUIResolve[src, args] passes arguments to the interface ...

Resolving Arbitrary Objects (GUIKit Package Tutorial)

Even though the GUIKit widget expression was designed with user interface issues in mind, you can construct object trees unrelated to user interface widgets and still take ...
