Solve Calculations - Casio fx-FD10 Pro User Manual

Under initial default settings, this calculator automatically simplifies fraction calculation results
before displaying them. Before performing the following examples, use the Setup screen to
change the "Simplify" setting from "Auto" to "Manual" (page 2-15).
i
• When "a+b " or "
calculation results always are simplified before being displayed, even if the "Simplify" setting
is "Manual".
• If you want to simplify fractions manually (Simplify: Manual), make sure that the "Real" is
selected for the "Complex Mode" setting.
Example 1
Example 2
• 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
SOLVE uses approximation based on Newton's Law to solve equations.
The following is the syntax for using the Solve function.
f x n a
Solve( ( ), , ,
An error (Time Out) occurs when there is no convergence of the solution.
• 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.
