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.
Example 2 To determine the maximum value for the interval defined by start
point
a = 0 and end point b = 3, with a precision of n = 6 for the
function y = –x
