InflectionPoints

  

find the inflection points of an expression

 

Calling Sequence

Parameters

Description

Examples

Calling Sequence

InflectionPoints(f(x), x, opts)

InflectionPoints(f(x), x = a..b, opts)

InflectionPoints(f(x), a..b, opts)

Parameters

f(x)

-

algebraic expression in variable 'x'

x

-

name; specify the independent variable

a, b

-

algebraic expressions; specify restricted interval for inflection points

opts

-

equation(s) of the form numeric=true or false; specify computation options

Description

• 

The InflectionPoints(f(x), x) command returns all inflection points of f(x) as a list of values.

• 

The InflectionPoints(f(x), x = a..b) command returns all inflection points of f(x) in the interval [a,b] as a list of values.

• 

If the independent variable can be uniquely determined from the expression, the parameter x need not be included in the calling sequence.

• 

An inflection point is defined as any point at which the sign of the second derivative changes.

• 

If the expression has an infinite number of inflection points, a warning message and sample inflection points are returned.

• 

The opts argument can contain the following equation that sets computation options.

  

 

  

numeric = true or false

  

Whether to use numeric methods (using floating-point computations) to find the inflection points of the expression. If this option is set to true, the points a and b must be finite and are set to  and  if they are not provided. By default, the value is false.
