Note For equations that use a placeholder variable—

such as an integral, summation, or derivative, the

placeholder variable will have a label displayed.

However, you will not be able to solve for a

placeholder variable.

If one or more of the variables does not already exist, it will be created

and added to the current directory when you solve the equation the

first time.

To enter a value for a known variable:

unknowm variable.

2. Type in the guess value and press f ENTER),

To solve for an unknown variable:

1, Move the highlight to the field labeled with the name of the

unknown variable,

2, Press SOLVE. The result wull be displayed in the field and a

labeled copy put on the stack.

Interpreting Results

The SOLVE application returns a message describing the result of the

root-finding process. You can use this message and other information

to judge whether the result is a root of your equation.
