Higher-order derivative test
- Higher-order derivative test
-
In mathematics, the higher-order derivative test is used to find maxima, minima, and points of inflexion for sufficiently differentiable functions.
The test
Let ƒ be a differentiable function on the interval I and let c be a point on it such that
- exists and is non-zero.
Then,
- if n is even
- is a point of local maximum
- is a point of local minimum
- if n is odd is a point of inflection.
