• An error occurs if simplification cannot be performed using the specified divisor.
• Executing
'Simp while a value that cannot be simplified is displayed will return the original
value, without displaying “F=”.
k Solve Calculations [OPTN] - [CALC] - [Solve]
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 4-4.
• You cannot use a quadratic differential, Σ , maximum/minimum value or Solve calculation
expression inside of any of the above functions.
• Pressing A during calculation of Solve (while the cursor is not shown on the display)
interrupts the calculation.
