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 context-sensitive menus.  Step-by-step examples are included to enhance your understanding.

Refer to Help > Quick Reference for basic getting started tips.

Tools and Features

This section details the point-and-click tools and core features available in Maple to help you accomplish tasks quickly and easily. These features include palettes, context sensitive menus, 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 , similar 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. Alternatively, navigate to View → Palettes → Arrange Palettes... to show, hide, and rearrange palettes interactively. Note that as more palettes are enabled, you may want to display some palettes to the right of the Maple workspace.

One of the most useful features in Maple is the Context-Sensitive Menu, or Context Menu. Together with inline evaluation, the use of Context Menus is one of the fastest ways to perform a string of successive computations.

To access the Context Menu menu for a specific Maple object, right-click the object. The Menu will contain common operations associated with the object; for example, the Context Menu for a matrix will include the inverse operation, and for an expression, the Menu 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 .

 Step Description Illustration 1 Right-click any part of the expression (within the dotted outline) and a Context Menu is displayed. Select Collect → Name → x. 2 Right-click on the resulting expression and select Simplify>Simplify. 3 Right-click on the resulting expression and select Factor. Note If you were working with an equation, some of these functionalities would not be available. Equations cannot be simplified or explicitly differentiated and must therefore first be converted into an expression. To do this, right-click the equation and select Right-hand 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 re-numbered 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 three-by-four 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 enter the equation label, either press Ctrl + L or select Insert → Label.... Type the label value into the dialogue box; in this case, since it is the first labeled result, the label value is $1$. Click OK. Now type a right parenthesis [ ) ]. 4 Press Enter. The reduced row echelon form of this Matrix is displayed and labeled.

Assistants

Maple has many interactive assistants that provide graphical user interfaces to various Maple packages and functionalities. Here are some of the assistants available in Maple.

 Back-Solver Solve for an unknown parameter in an equation whose other parameters are known Curve Fitting Compute regressions and fit curves on a collection of data Data Analysis Display textual and graphical information about data sets, traverse data sets, and generate new data sets via standard operations on existing ones Equation Manipulator Perform a series of operations on an equation Import Data Import data from an external file into Maple as an rtable Installer Builder Build installers for your own toolboxes, or return a Build command which you can store and execute later Library Browser Manipulate the libraries in a specified directory ODE Analyzer Investigate and solve ordinary differential equations and ordinary differential equation systems Optimization Graphically minimize or maximize an objective function under given constraints Plot Builder Build a Maple plot interactively Scientific Constants Browse an extensive collection of physical constants and properties of chemical elements Special Functions View properties of over 200 special mathematical functions Thermophysical Properties Calculator Calculate state-dependent and state-independent properties for pure fluids, mixtures, certain incompressible fluids and the properties of humid air Units Calculator Convert between over 500 units of measurement

 Maple Help Maple's help system provides extensive help on topics and commands in Maple. Access the help system from the Help > Maple Help menu item or enter a query in the search box in the worksheet toolbar and then press Enter.   Tip: You can also put your cursor in a word and press F2 to get help on that word.
