Enter Expressions in Maple Worksheets

 The following assumes that the Input display option is set to Maple Notation (that is, 1-D math) in the Display tab of the Options dialog. For details, see Options>Display.
 • For information on using the default 2-D math mode in worksheets, see 2-D Math.
 • For information on using palettes to enter expressions and symbols, see Overview of Palettes.

Entering Expressions as Maple Input

 Enter Maple commands at the Maple prompt. Maple recognizes your entry as Maple input and executes the command.
 1 Enter the Maple input, followed by either a semicolon, no punctuation, or a colon.
 2 Press the Enter key.

Example 1: Maple Input Followed by Either a Semicolon or No Punctuation

 You can use a semicolon or no punctuation to terminate a Maple input command and generate the output as shown:
 > factor(x^2 + 2*x + 1);
 ${\left({x}{+}{1}\right)}^{{2}}$ (1)
 > factor(x^2 + 2*x + 1)
 ${\left({x}{+}{1}\right)}^{{2}}$ (2)

Example 2: Maple Input Followed by a Colon

 If the input ends with a colon, the result is computed but not displayed.
 > factor(x^2 +2*x +1):

Assigning Expressions to Names

 Assign a Maple expression to a name so that you can use the expression again in subsequent calculations.
 > expn := 3 * sin(x) + 2 * cos(x);
 ${\mathrm{expn}}{:=}{3}{}{\mathrm{sin}}{}\left({x}\right){+}{2}{}{\mathrm{cos}}{}\left({x}\right)$ (3)
 > sin(x) * expn;
 ${\mathrm{sin}}{}\left({x}\right){}\left({3}{}{\mathrm{sin}}{}\left({x}\right){+}{2}{}{\mathrm{cos}}{}\left({x}\right)\right)$ (4)
 You can also assign equations to names.
 > eqn := y = 5*x - 3;
 ${\mathrm{eqn}}{:=}{y}{=}{5}{}{x}{-}{3}$ (5)
 > f := x -> x * 2;
 ${f}{:=}{x}{→}{2}{}{x}$ (6)
 > f(3);
 ${6}$ (7)
 > f(y + 1);
 ${2}{}{y}{+}{2}$ (8)

Making Maple Commands Inert

 As you develop your worksheet, you can use inert Maple commands to help identify each step of the problem-solving process or to delay evaluation.

Examples of Maple Functions

 Maple functions include most standard mathematical functions such as sin, sinh, arcsin, exp, ln, sqrt, and binomial.
 •
 More advanced Maple functions include the differential operator, the sequence function, and the composition function.

Examples of Maple Objects

 Maple objects include expression sequences, lists, and sets.
