The following describes the items that are available in the menus you use when performing 
differential/quadratic differential, integration, 

 Σ, maximum/minimum value, and Solve 

calculations.

When the option menu is on the display, press 

4(CALC) to display the function analysis 

menu. The items of this menu are used when performing specifi c types of calculations.

k Solve Calculations

The following is the syntax for using the Solve function in a program.

Solve(  

 f( x),  n,  a,  b)            ( a: lower limit,  b: upper limit,  n: initial estimated value)

There are two different input methods that can be used for Solve calculations: direct 
assignment and variable table input.

With the direct assignment method (the one described here), you assign values directly to 
variables. This type of input is identical to that used with the Solve command used in the 
PRGM mode.

Variable table input is used with the Solve function in the EQUA mode. This input method is 
recommended for most normal Solve function input.

An error (Time Out) occurs when there is no convergence of the solution. 

For information about Solve calculations, see page 4-3-1.
