Quadratic Differential Applications
• Arithmetic operations can be performed using two quadratic differentials.
Therefore:
f ''
(
a
)
+ g''
(
a
),
f ''
(
a
)
×
g''
(
a
), etc.
• The result of a quadratic differential calculation can be used in a subsequent arithmetic
or function calculation.

f ''
(

log (
f ''
(

) ), etc.
• Functions can be used within the terms (
f
(
x
)
,
a
,
tol
) of a quadratic differential expression.

# In the Math input mode, the tolerance value is
fixed at 1
E
-10 and cannot be changed.
# The rules that apply for linear differential also
apply when using a quadratic differential
calculation for the graph formula (see page 2-
5-2).
# Inaccurate results and errors can be caused
by the following:
- discontinuous points in
x
values
- extreme changes in
x
values
- inclusion of the local maximum point and
local minimum point in
x
values
- inclusion of the inflection point in
x
values
- inclusion of undifferentiable points in
x
values
- differential calculation results approaching
zero
# You can interrupt an ongoing quadratic differential
calculation by pressing the
A
key.
# Always use radians (Rad mode) as the angle unit
when performing trigonometric quadratic
differentials.
# You cannot use a differential, quadratic differen-
tial, integration,
Σ
, maximum/minimum value,
Solve, RndFix or log ab calculation expression
inside of a quadratic differential calculation term.
# With quadratic differential calculation, calculation
precision is up to five digits for the mantissa.
