Palettes are like extensions of your keyboard. They can be used to perform many actions in Mathematica, including entering typesetting characters, styling notebooks, and ...

"Manipulating Elements of Lists" shows how you can pick out elements of lists based on their positions. Often, however, you will need to select elements based not on where ...

EulerE[n] gives the Euler number E_n. EulerE[n, x] gives the Euler polynomial E_n (x).

HypergeometricU[a, b, z] is the confluent hypergeometric function U(a, b, z).

WhittakerM[k, m, z] gives the Whittaker function M k, m (z).

HankelH2[n, z] gives the Hankel function of the second kind H_n^(2)(z).

Simplify[expr] performs a sequence of algebraic and other transformations on expr, and returns the simplest form it finds. Simplify[expr, assum] does simplification using ...

HornerForm[poly] puts the polynomial poly in Horner form.HornerForm[poly, vars] puts poly in Horner form with respect to the variable or variable list ...

Module[{x, y, ...}, expr] specifies that occurrences of the symbols x, y, ... in expr should be treated as local. Module[{x = x_0, ...}, expr] defines initial values for x, ...

Power series are in many ways the algebraic analog of limited-precision numbers. Mathematica can generate series approximations to virtually any combination of built-in ...
