Combining With The Function Memory - Casio FX-730P Owner's Manual

7-10 Combining with the Function Memory
A practical method of using the DATA BANK function is to use it in combina-
tion with the Function Memoiy . Store formulas and equations in the DAT A
BANK and press the
~
key to call the desired formula or equation. And
calculate by storing the retrieved formula in the Function Memory by pressing
the
~key.
Assume that the following formula and equation are stored in the DAT A BANK.
1
QUADRATIC EQUATION
r
X=<-B+SQR(Bf2-4*A*Cll/(2*A>:
X=<-B-SQR<B
2
t2-4*A*Cll/(2*A>
3
HERON
4 s·s·=<A+B+Cl/2:S=SQR<S*<S-A>*<S-B>*<S-C))
A formula to calculate the root of a quadratic equation and Heron's formula are
stored in the DATA BANK.
Now, calculate the root of the quadratic equation. Press
(Q]~
to search the
quadratic equation.
After confirming the name, press
the~
key and the calculation formula is dis-
played.
IX=(-B+SQR(Bt2-4+A+C))/(21
Then store the calculation formula in the Function Memory.
