VertexColors is an option for graphics primitives which specifies the colors to assign to vertices.
VertexQ
(Built-in Mathematica Symbol) VertexQ[g, v] yields True if v is a vertex in the graph g and False otherwise.
VertexShape is an option and property for Graph and related functions that specifies the graphics used for vertices.
$MessagePrePrint is a global variable whose value, if set, is applied to expressions before they are included in the text of messages.
Now that we have introduced the basic features of patterns in Mathematica, we can use them to give a more or less complete example. We will show how you could define your own ...
Just as Mathematica allows you to define how expressions should be evaluated, so also it allows you to define how expressions should be formatted for output. The basic idea ...
The general solution to a differential equation contains undetermined coefficients that are labeled C[1], C[2], and so on. This example has one undetermined parameter, C[1]. ...
There are four major areas in the study of ordinary differential equations that are of interest in pure and applied science. Of these four areas, the study of exact solutions ...
DSolve can find solutions for most of the standard linear second-order ODEs that occur in applied mathematics. Here is the solution for Airy's equation. Here is a plot that ...
"Defining Variables" discussed assignments such as x=y which set x equal to y. Here we discuss equations, which test equality. The equation x==y tests whether x is equal to ...
