Formulas

The Formula dialog provides a way to enter an expression and a Maple operation. What appears on the screen is the result of the operation and depends upon active definitions of variables that appear in the formula. Formulas remain active in your document–that is, changing definitions of relevant variables will change the data on the screen.

When Helper Lines are turned on, a Formula is identified by a yellow background.

$\blacktriangleright$ To insert a formula

  1. ClickitbpF0.3208in0.3208in0.0701informula.wmf on the Field toolbar

    - or -


    From the Insert menu, choose Field and then choose Formula.

  2. In the Formula area, enter a mathematics expression.

  3. In the Operation area, enter the operation you want to perform on the expression. (Click the arrow to the right for a list of available operations.)

  4. Choose OK.


Scientific Notebook displays the results of the operation on the screen.

  1. For which values of the variable x is $\limfunc$a1x - $\limfunc$b1 < 0?

    1.  x < $\limfunc$b1/$\limfunc$a1

    2.  x > $\limfunc$b1/$\limfunc$a1

    3.  x > $\limfunc$b1

    4.  x < $\limfunc$b1

    5.  None of these

First variation: Define $\limfunc$a1 = 2 and $\limfunc$b1 = 5 by placing the insertion point in each equation and choosing Define + New Definition.


  1. For which values of the variable x is x - < 0?

    1.  x < /

    2.  x > /

    3.  x >

    4.  x <

    5.  None of these

After printing a quiz, make different definitions for $\limfunc$a1 and $\limfunc$b1 to obtain additional variations of the quiz.
