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

Input

AK4(CALC)6(g)2(FMax) -vx+cv+c,
Input the interval
a
= 0,
b
= 3.
a,d,
Input the precision
n
= 6.
g)
w
# In the function
f
(
x
), only X can be used as
a variable in expressions. Other variables
(A through Z excluding X,
r
,
Ƨ
) 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
fl uctuation 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.
