Like everything else in Mathematica, notebooks are ultimately symbolic expressions. When you edit notebooks—or apply high-level programmatic functions—Mathematica ...

In doing a calculation with Mathematica, you usually go through a sequence of steps. If you want to, you can do each step on a separate line. Often, however, you will find it ...

When Mathematica reads the text x^y, it interprets it as x raised to the power y. In a notebook, you can also give the two-dimensional input x^y directly. Mathematica again ...

The fundamental operation that Mathematica performs is evaluation. Whenever you enter an expression, Mathematica evaluates the expression, then returns the result. Evaluation ...

Principles of Evaluation Reducing Expressions to Their Standard Form Attributes

The time it takes Mathematica to perform a computation is important information that can help you write efficient programs. Conveniently, you can display the time elapsed for ...

Evaluating sums. Mathematica recognizes this as the power series expansion of e^x. This sum comes out in terms of a Bessel function.

Much of what Mathematica does revolves around manipulating structured expressions. But you can also use Mathematica as a system for handling unstructured strings of text. ...

CDFWavelet[] represents a Cohen\[Dash]Daubechies\[Dash]Feauveau wavelet of type "9/7". CDFWavelet["type"] represents a Cohen\[Dash]Daubechies\[Dash]Feauveau wavelet of type " ...

ComplexityFunction is an option for Simplify and other functions which gives a function to rank the complexity of different forms of an expression.
