Numerical Calculations

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 = –x2+ 2x + 2

Input 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.

#In the function f (x), only X can be used as a variable in expressions. Other variables (A through Z excluding X, 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 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 Akey.

#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.
