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

• 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).
