The Solve Aplet - HP 39gs Quick Start Manual

Table 1- 1 Function Aplet Summary
Press SHIFT followed by NUM to enter the Numeric Setup. This view helps you manually
control the appearance of the table. The fields are:
• NUMSTART: the first value of x shown in the table
• NUMSTEP: the common difference between consecutive x-values
• NUMTYPE: choose between table types:
• Automatic: provides x- and function-values
• Build Your Own: you supply x-values; the Aplet provides the corresponding
function-values
• NUMZOOM: the zoom factor for zooming
• EDIT: edit the current value in a field
• : sets NUMSTART and NUMSTEP so that the table shows the same values as the
tracing cursor in the Plot view

The Solve Aplet

The Solve Aplet lets you define up to ten equations, each using as many variables as you like. Although you can only solve one equation at a time, you
can solve for any of its variables. If an equation has more than one possible solution for one of its variables, you can enter a seed value to retrieve the
solution you want. If two or more of your equations share one or more variables, then the current or solved values of those variables are carried over as
you move from one equation to the other. Table 1-2 summarizes the functionality of the Solve Aplet. Press the APLET key, scroll down to select the Solve
Aplet, and press the START menu key to get started. Like the Function Aplet, the Solve Aplet starts in the Symbolic view.
