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 .
u Minimum Value
K 4 (CALC)6 (g )1 (FMin) f
( x ) , a , b , n )
(
a : start point of interval, b : end point of interval, n : precision ( n = 1 to 9))
u Maximum Value
K 4 (CALC)6 (g )2 (FMax) f
( x ), a , b , n )
(
a : start point of interval, b : end point of interval, n : precision ( n = 1 to 9))
Example 1 To determine the minimum value for the interval defi ned by start
point
a = 0 and end point b = 3, with a precision of n = 6 for the
function y = x
2
– 4 x + 9
Input
f
( x ).
A K 4 (CALC)6 (g )1 (FMin) vx -e v +j,
Input the interval
a = 0, b = 3.
