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.

Entering Expressions as Maple Input
Examples of Maple Functions
Examples of Maple Objects
Enter Maple commands at the Maple prompt. Maple recognizes your entry as Maple input and executes the command.
Enter the Maple input, followed by either a semicolon, no punctuation, or a colon.
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);
${\left({x}{+}{1}\right)}^{{2}}$
factor(x^2 + 2*x + 1)
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);
${\mathrm{expn}}{\u2254}{3}{}{\mathrm{sin}}{}\left({x}\right){+}{2}{}{\mathrm{cos}}{}\left({x}\right)$
sin(x) * expn;
${\mathrm{sin}}{}\left({x}\right){}\left({3}{}{\mathrm{sin}}{}\left({x}\right){+}{2}{}{\mathrm{cos}}{}\left({x}\right)\right)$
You can also assign equations to names.
eqn := y = 5*x - 3;
${\mathrm{eqn}}{\u2254}{y}{=}{5}{}{x}{-}{3}$
Define your own functions.
f := x -> x * 2;
${f}{\u2254}{x}{\mapsto}{2}{}{x}$
f(3);
${6}$
f(y + 1);
${2}{}{y}{+}{2}$
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.
Active and Inert Functions
Maple functions include most standard mathematical functions such as sin, sinh, arcsin, exp, ln, sqrt, and binomial.
Index of Maple Functions
More advanced Maple functions include the differential operator, the sequence function, and the composition function.
Examples of Advanced Maple Functions
Maple objects include expression sequences, lists, and sets.
