1.5 Entering Expressions in Maple 1.5 Entering Expressions in Maple To enter expressions at the prompt, use the keyboard, the palettes, or both Using the keyboard is the most direct method, but the palettes enable you to enter a command without knowing its syntax There are two types of input display. Use Maple Notation to display input as Maple syntax. Maple Notation is the default. Use Standard Math Notation to display input in typeset notation as it appears in a textbook These examples step you through entering sin(x)dr in various ways To enter the integral in Standard Math Notation by using the palettes 1. Display the palettes, if necessary. From the View menu, choose Palettes, then Show All Palettes. The Symbol, Expression, Matrix, and Vector palettes are displayed. Move the palettes to the side of the worksheet, if 2. If required, change the input to Standard Math Notation. (If there is a question mark(?)after the prompt, the input is already set to Standard Math Notation. )At the prompt, right-click. The context-sensitive menu is displayed. Choose Standard Math 3. On the Expression palette, click. The integral symbol appears,and the question mark placeholder is selected 4. On the Expression palette, click sin The function sin appears, with another placeholder 5. Enter x(on the keyboard), and press Tab to go to the next placeholder Repeat step 5 7. Enter 0(zero), and press TAB 8. On the Symbol palette, clickz. (It is in the bottom row.) 9. Press enter Your worksheet should resemble that of Figure 1-B on page 61.5 Entering Expressions in Maple • 5 1.5 Entering Expressions in Maple To enter expressions at the prompt, use the keyboard, the palettes, or both.
