Numerical Calculations

k Maximum/Minimum Value Calculations [OPTN]-[CALC]-[FMin]/[FMax]

After displaying the function analysis menu, you can input maximum/minimum calculations

using the formats below, and solve for the maximum and minimum of a function within

interval a < x < b. (a: start point of interval, b: end point of interval, n: precision (n = 1 to 9))

uMinimum Value

K4(CALC)f(FMin) f(x) , a , b , n )

uMaximum Value

K4(CALC)g(FMax) f(x), a , b , n )

Example 1 To determine the minimum 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

– 4x + 9

Input f(x).

AK4(CALC)f(FMin) vx-ev+j,

Input the interval a = 0, b = 3.

a,d,

Input the precision n = 6.
