Sharp EL-376SB - Manual (Page 8)

Constant and Chain Calculation functions are popular in general electronic calculators as
they allow equations to be entered without having to key repeatedly. Confusion may arise
however, as not all scientific calculators show the equation being equal to the answer in the
formula display. With SHARP's scientific calculators, the figures you omit are automatically
shown as K (constant) or ANS (answer)*. Contradictions between equations and answers are
eliminated and calculations are easier and more logical to enter.
Greater Efficiency and Ease of Use
Direct Algebraic Logic (D.A.L.)
Until the introduction of SHARP's D.A.L., keying in equations had been a
complicated process making scientific calculators difficult to use. Introduced in
1992 and an industry-first, SHARP's D.A.L. allows symbols and numbers of an
equation to be entered as they are written. Instead of wasting energy on difficult
calculator operations, users are free to concentrate on mathematical concepts.
• Numerical Derivative
X=-2
dx=0.001
You can calculate the same derivative calculation repeatedly without having to input the formula again.
• Numerical Integral
You can calculate the same integral calculation repeatedly without having to input the formula again.
[2, 3]
n=100
Simply enter numerical values following the interactive on-screen instructions, and
you can find the answer easily of derivative and integral calculations. You don't have
to re-enter the formula, and the calculation can be repeated as many times as needed.

Chain Calculation
Chain (ANS)
A portion of the equation is
automatically memorised as a constant,
thus omitting redundant input.
Constant (K )

Numerical Derivative/Integral
2-Line Display
A 2-line display allows the users to check
the equation and answer at the same
time. Because the equation remains on
display, it is easy to edit or make
substitutions if necessary.

Matrix Function
SHARP's Multi-Line Playback function lets you recall any of the last 142 steps you have
made. This feature is very useful for
comparing formulas and recalculating equations.

Constant/Chain Calculations
Note: Even when the power is off, the
equation will remain in memory until a new
equation is stored.
(1) Store the equation into the calculator.
How to use it
(2) Call up the equation.
(3) Use the equation to
calculate.

*Formulas up to 256 characters in length can be stored in F1–F4.
Frequently used formulas or complex equations can be stored as functions in
Formula Memory*. By recalling the formula, you can substitute new variables into
the equation and recalculate it without having to enter the entire sequence again.
Since you can do repeat equations, it's also convenient for simulations.

This function enables calculation of a variable in a given equation. Other
variables (a, b, c, etc.) must already be defined in order to calculate .
Equation "sin – 0.5" (DEG)
In addition to the four basic arithmetic functions (excluding division between
matrices),
3 , 2 , and -1 , users are provided with transpose and cumulative matrix
functions, among others. Up to four matrices can be saved in memory, each up to
four rows by four columns in size.
You have to push the keys in a different order than the
actual equation, making the input process confusing. You push the keys in the sam
as the actual equation.
