How Do I...
Go to Maple Portal
Maple's Tutorials are designed to help you get started with Maple, learn about the key tools available in Maple, and lead you through a series of problems.
The How do I... topics cover essentials for doing mathematics in Maple. Learn more about Maple's tools and features, such as palettes and the Context Panel. Stepbystep examples are included to enhance your understanding.
Refer to Help > Quick Reference for basic getting started tips.

Tools and Features


This section details the pointandclick tools and core features available in Maple to help you accomplish tasks quickly and easily. These features include palettes, the context panel, and assistants.

Palettes


Maple has over thirty palettes containing an extensive collection of symbols, templates, and other features. These palettes are located beside the Maple workspace.
A template is an editable expression containing placeholders that can be easily overwritten. Use the Tab key to move to and highlight the next placeholder in a template, and Shift + Tab to move back to the previous placeholder. The How do I... section contains many examples where a template from a palette is used.
•

The Expression palette contains many common mathematical expressions—such as exponents, subscripts, $n$th roots, elementary functions, operators, and piecewise functions—as easily editable templates. See the How do I... subsection on entering a simple expression for an example of its use.

The Calculus palette, similarly to the Expression palette, contains buttons for constructing expressions—such as integrals, derivatives, dot derivatives, etc.
•

The Matrix palette is a tool used to insert a matrix template of a specified size, type, shape, and data type for entering a matrix quickly. See the How do I... subsection on entering a matrix for an example of its use.

By default, not all palettes are shown; to show a hidden palette, navigate to View / Palettes / Show Palette, and select a palette. For more information, see the Arrange Palettes help page.

The Context Panel


One of the most useful features in Maple is the Context Panel, which offers contextsensitive options for the current selection. Together with inline evaluation, the use of the Context Panel is one of the fastest ways to perform a string of successive computations.
To access the context panel for a specific Maple object:
1.

Make sure that the context panel toggle is clicked to open the context panel (in other words, with the context panel open the toggle should look like this:
)

2.

Click the object. The context panel opens and contains common operations associated with the object; for example, the context panel for a matrix will include the inverse operation, and for an expression, the context panel will contain the simplify operation.

Before you proceed with the example below, be sure to familiarize yourself with entering simple mathematical expressions (see the How do I... subsection on entering a simple expression). Open a new worksheet in Document mode, and ensure that you are in Math mode.

Example: simplify and factor


Follow the steps below to simplify and factor the expression $\mathrm{sin}{\left(x\right)}^{2}\cdot {x}^{2}\+\mathrm{cos}{\left(x\right)}^{2}\cdot {x}^{2}plus;2xplus;1$.
Step

Description

Illustration

1

Click any part of the expression (within the dotted outline) and the context panel is displayed. Select Collect / Name / x.


2

Click on the resulting expression and in the context panel select Simplify>Simplify.


Note

If you were working with an equation, some of these functionalities would not be available. In such a case, you might be able to start by rewriting as an equation equal to zero and then working with the expression on the lefthand side.

Command Completion


Command and symbol completion is a feature that automatically suggests a command to use as you enter a phrase in Maple. To access the command completion menu, press Esc after typing the phrase. A popup list displays commands that begin with the phrase typed. Maple lists symbols, commands, functions, and package names that match the entered text. To insert an item from this list, select it with the mouse or navigate to it by using the arrow keys and press Enter.
For example, to get the Greek letter $\mathrm{\ρ}$ (rho), type rho and press Esc. Select $\mathrm{\ρ}\.$
This command completion list can include command completion templates. These provide the full syntax of common Maple commands including arguments, so that these commands can be easily entered. Simply choose the desired command completion template and replace the placeholders with the desired values.
For example, to get an integral, type int and press Esc. Select int(definite)$\.$

Equation Labels


Equation Labels are automatically generated after executing a Maple command on a new line. The result returned is labeled so that you can refer to it later in the document. As an example, compute the reduced row echelon form of a matrix using equation labels. Maple's equation labels are automatically renumbered in sequential order if any labeled result is deleted or moved.
Before you proceed with the example below, be sure to familiarize yourself with entering simple mathematical expressions (see the How do I... subsection on entering a simple expression). Open a new worksheet in Document mode, and ensure that you are in Math mode.

Computing the reduced row echelon form of a matrix


Follow the steps below to find the reduced row echelon form of the threebyfour matrix $\left[\begin{array}{cccc}1& 2& 3& 6\\ 4& 5& 6& 15\\ 7& 8& 9& 24\end{array}\right]$.
Step

Description

Illustration

1

Follow the instructions in either of the two examples given in the How do I subsection on entering matrices. Press Enter, and the resulting Matrix is labeled.


2

Type $\mathrm{LinearAlgebra}\[\mathrm{ReducedRowEchelonForm}\]$.


3

Now pass the Matrix as an argument to this procedure by typing a left parenthesis [(], followed by the equation label. To insert the equation label, doubleclick the label number of the matrix in step 1. Now type a right parenthesis [ ) ].


4

Press Enter. The reduced row echelon form of this Matrix is displayed and labeled.


Note

An alternative way to enter the equation label is to use the shortcut key Ctrl + L and then type the label value into the Identifier field; in this case, since it is the first labeled result, the label value is $1$.${}$
