Mathematica's unified symbolic architecture makes it straightforward to add toolbars with any possible appearance and action to any Mathematica notebook.

MatrixPower[m, n] gives the n\[Null]\[Null]^th matrix power of the matrix m. MatrixPower[m, n, v] gives the n\[Null]^th matrix power of the matrix m applied to the vector v.

Thickness[r] is a graphics directive which specifies that lines which follow are to be drawn with thickness r. The thickness r is given as a fraction of the horizontal plot ...

One of the important features of Mathematica is that it can do symbolic, as well as numerical calculations. This means that it can handle algebraic formulas as well as ...

SortBy[list, f] sorts the elements of list in the order defined by applying f to each of them.

Union[list_1, list_2, ...] gives a sorted list of all the distinct elements that appear in any of the list_i. Union[list] gives a sorted version of a list, in which all ...

StieltjesGamma[n] gives the Stieltjes constant \[Gamma]_n. StieltjesGamma[n, a] gives the generalized Stieltjes constant \[Gamma]_n (a).

Rectangle[{x_min, y_min}, {x_max, y_max}] is a two-dimensional graphics primitive that represents a filled rectangle, oriented parallel to the axes. Rectangle[{x_min, y_min}] ...

The ability to define and use your own functions is part of what gives Mathematica such power. It is often inconvenient to have to explicitly name a function for every small ...

If you have an equation like 2x==0, it is perfectly clear that the only possible solution is x->0. However, if you have an equation like ax==0, things are not so clear. If a ...
