UNIQUE FUNCTIONS
2. Solver Function
• The EL-9650 is equipped with a solver function that allows a known variable to be
input to solve an unknown variable. Hence it is possible to solve an equation using
various variables.
• Only real numbers may be used in the solver function.
<Example>
In the equation Y = A + B, Y and B are known variables with values 2 and 5, respec-
tively. The value of A will be calculated.
1. Delete the screen.
Press
¬
.
2. The display on the right will flash momentarily when
pressing
Ï
to inform that it is in the solver
mode.
3. Enter the equation:
Press
ÅYÅ=ÅA+ÅB
®
.
4. Input the known variables:
Input 2 for Y.…2
®
Skip A since it is the unknown variable…
®
Input 5 for B.…5
®
Move the cursor to the location of the unknown
variable A…
≤
5. Execute the solver function.
Press
Ï
.
It is simple to use the solver function by inputting
known variables when there is only one unknown
variable. See CHAPTER 9 on page 211 for details.
*
After the solution has been found, press
¬
to return to
the variable input screen. On this screen, you may change
the numeric values in the variables and select another
unknown variable to find the solution again.
