TextCell["string"] gives a text cell that can appear in a Mathematica notebook.TextCell["string", " style"] gives a text cell with the specified style.

Whenever Mathematica draws a three-dimensional object, it always effectively puts a cuboidal box around the object. With the default option setting Boxed->True, Mathematica ...

Conventions for file names. Most files used by Mathematica are completely system independent. .mx and .exe files are however system dependent. For these files, there is a ...

Finding and setting values of symbols. Mathematica effectively stores all definitions you give as lists of transformation rules. When a particular symbol is encountered, the ...

It is often useful to carry out a numerical integration using fixed step sizes. For example, certain methods such as "DoubleStep" and "Extrapolation" carry out a sequence of ...

Simplifying expressions. Mathematica does not automatically simplify an algebraic expression like this. Simplify performs the simplification.

SendDelegateArguments is an option to AddEventHandler and NETNewDelegate that specifies which of the delegate arguments you want to be passed to your Mathematica callback ...

TabView[{lbl_1 -> expr_1, lbl_2 -> expr_2, ...}] represents an object in which clicking the tab with label lbl_i displays expr_i. TabView[{lbl_1 -> expr_1, lbl_2 -> expr_2, ...

Numerical algorithms for constrained nonlinear optimization can be broadly categorized into gradient-based methods and direct search methods. Gradient-based methods use first ...

Manipulate[expr, {u, u_min, u_max}] generates a version of expr with controls added to allow interactive manipulation of the value of u. Manipulate[expr, {u, u_min, u_max, ...
