2-5 Numerical Calculations
The following describes the items that are available in the menus you use when performing
differential/ quadratic differential, integration, $&'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 specific types of calculations.

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 recommend for most normal Solve function input.
An Error (Iteration ERROR) occurs when there is no convergence of the solution.
