Use the Expression and Calculus Palettes

The Expression palette contains buttons for constructing expressions such as products, exponents, subscripts, and piecewise functions.

Similarly, the Calculus palette contains buttons for constructing expressions such as limits, derivatives and integrals.

 

Using the Expression or Calculus Palette

Augmenting versus Replacing Expression Items

Entering a Subscript Using the Expression palette

Using the Expression or Calculus Palette

To use the Expression or Calculus palette:

1. 

Display the Expression (or Calculus) palette. See Show Palettes.

2. 

In the worksheet, click where the expression is to be inserted.

3. 

On the palette, select the template for the expression you want to enter.

4. 

Fill in the first placeholder by entering a number, a symbol, or an expression.

5. 

Press the Tab key to move the cursor to the next placeholder. Important: Ensure that your Tab key is set to move to the next placeholder and not indent. For details, see Using the Tab Key.

6. 

Continue filling all placeholders that apply to your expression.

7. 

When all of the relevant placeholders have been filled, press the Enter key.

Augmenting versus Replacing Expression Items

  

If you select a math expression and click an item on the expression palette, then Maple either replaces the original selection or builds on it.

  

For example, consider this example:

1. 

Enter the following expression.

2. 

Select the entire expression and click the exponent button on the Expression palette.

3. 

The brackets are inserted along with a placeholder for the exponent.

Entering a Subscript Using the Expression palette

There are two subscript entities in the Expression Palette.  

• 

Literal subscript: From the Expression palette, select (tooltip: a_n;). Literal subscripts, also known as subscripted variable names, are useful if you want to identify x and x0 as separate variables, for example.

• 

Indexed subscript: From the Expression palette, select (tooltip: a[n];). The indexed subscript refers to an element of a base, for example, x1 is the first element of x (which may be a list, for example).
