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
:
