NonConstants is an option for D which gives a list of objects to be taken to depend implicitly on the differentiation variables.

StackBegin[expr] evaluates expr, starting a fresh evaluation stack.

StackComplete[expr] evaluates expr with intermediate expressions in evaluation chains included on the stack.

StackInhibit[expr] evaluates expr without modifying the evaluation stack.

The GUIKit framework makes it relatively easy to reuse interface definitions because of its automatic use of private symbol contexts for each instance of a definition. There ...

PossibleZeroQ[expr] gives True if basic symbolic and numerical methods suggest that expr has value zero, and gives False otherwise.

LayeredGraphPlot attempts to draw the vertices of a graph in a series of layers, placing dominant vertices at the top, and vertices lower in the hierarchy progressively ...

NDSolve[eqns, y, {x, x_min, x_max}] finds a numerical solution to the ordinary differential equations eqns for the function y with the independent variable x in the range ...

A linear ODE with constant coefficients can be easily solved once the roots of the auxiliary equation (or characteristic equation) are known. Some examples of this type ...

One significant advantage Mathematica provides is that it can symbolically compute derivatives. This means that when you specify Method->"Newton" and the function is ...
