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

f(x).

• In the function f(x), only X can be used as a variable in expressions. Other
variables (A through Z, 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 following the precision value can be
omitted.
• Discontinuous points or sections with drastic fluctuation can adversely affect
precision 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/
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 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.
