fmin(
equation, lower limit of x, upper limit of x)
Returns the value of
variable x when the
equation Y has the
minimum value within
the specified range of
x
.
04 fmax(
fmax(equation,
lower limit of x, upper limit of x)
Return the value of variable x when the equation Y has
the maximum value within the specified range of x.
