64Example 2 To determine the maximum value for the interval defined by startpoint a = 0 and end point b = 3, with a precision of n = 6 for thefunction y = –x 2 + 2 x + 2Input f(x) .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. Othervariables (A through Z, r,θ) are treated as constants, and the value currentlyassigned to that variable is applied during the calculation.• Input of n and the closing parenthesis following the precision value can beomitted.• Discontinuous points or sections with drastic fluctuation can adversely affectprecision 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 italso 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 thanthe value you input for the start point (a). Otherwise an error is generated.• You can interrupt an ongoing maximum/minimum calculation by pressing theA key.• You can input an integer in the range of 1 to 9 for the value of n. Using anyvalue outside this range causes an error.3 - 5 Maximum/Minimum Value Calculations
