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
.
uMinimum Value

)
(
a
: start point of interval,
b

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
