fMax
Function: Returns the maximum point in a specific range of a function.
Syntax: fMax(Exp[,variable] [ ) ]
fMax(Exp,variable,start value,end value[,

• "
" is the default when you omit "[,variable]".
• Negative infinity and positive infinity are the default when the syntax fMax (Exp [,
variable] [ ) ] is used.
n
• "
" is calculation precision, which you can specify as an integer in the range of 1 to 9.
Using any value outside this range causes an error.
• This command returns an approximate value when calculation precision is specified for

n
= 4.
• Discontinuous points or sections that fluctuate widely can adversely affect precision or
even cause an error.
• Inputting a larger number for "
increases the amount of time required to perform the calculation.
• The value you input for the end point of the interval must be greater than the value you
input for the start point. Otherwise an error occurs.
