Time to learn something!
1. Go to Wikipedia.
2. Click on "Random article" in the left-hand sidebar box.

Here's what I got:
In mathematics, the higher-order derivative test is used to find maxima, minima, and points of inflection in an nth degree polynomial's curve.
Let f be a differentiable function on the interval I and let c be a point on it such that
;
- f(n)(c) 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
Oh, that's so obvious—like anyone would need to look that up!
