# In the function
f
(
x
)
, only X can be used as a
variable in expressions. Other variables (A
through Z excluding X,
r
,
θ
) are treated as
constants, and the value currently assigned to
that variable is applied during the calculation.
# Input of the tolerance (
tol
) value and the
closing parenthesis can be omitted. If you omit
tolerance (
tol
) value, the calculator automati-
cally uses a value for
tol
as 1
E
-10.
# Specify a tolerance (
tol
) value of 1
E
-14 or
greater. An error (Time Out) occurs whenever
no solution that satisfies the tolerance value
can be obtained.
# In the Math input mode, the tolerance value is
fixed at 1
E
-10 and cannot be changed.
# 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
