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 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

 1 Place your cursor at a Maple prompt ( ).
 2 Enter the Maple input, followed by either a semicolon, no punctuation, or a colon.
 3 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)
 Define your own functions.
 > f := x -> x * 2;
 ${f}{≔}{x}{↦}{2}{\cdot }{x}$ (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.
