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

• In the function
f(x)
, only X can be used as a variable in expressions. Other vari-
ables (A through Z,
r
,
θ
) are treated as constants, and the value currently as-
signed to that variable is applied during the calculation.
• Input of
n
and the closing parenthesis following the precision value can be omit-
ted.
• Discontinuous points or sections with drastic fluctuation can adversely affect pre-
cision or even cause an error.
• Note that you cannot use a Solve, differential, quadratic differential, integration,
maximum/minimum value or
Σ
calculation expression inside of a maximum/mini-
mum 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 Ma ERROR is generated.
• 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 (Arg ERROR).
