Numerical Calculations
# 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
n
and the closing parenthesis can be
omitted.
# Discontinuous points or sections with drastic
fluctuation can adversely affect precision or
even cause an error.
# You cannot use a differential, quadratic
differential, integration,
Σ
, maximum/minimum
value, Solve, RndFix or log ab calculation
expression inside of a maximum/minimum
calculation term.
# Inputting a larger value for
n
increases the
precision of the calculation, but it also increases
the amount of time required to perform the
calculation.
# The value you input for the end point of the
interval (
b
) must be greater than the value you
input for the start point (
a
). Otherwise an error
occurs.
# You can interrupt an ongoing maximum/
minimum calculation by pressing the
A
key.
# You can input an integer in the range of 1 to 9
for the value of
n
. Using any value outside this
range causes an error.
