Time to learn something!

1. Go to Wikipedia.

2. Click on "Random article" in the left-hand sidebar box.

3. Post it!

Here's what I got:

In mathematics, the

higher-order derivative testis used to find maxima, minima, and points of inflection in ann^{th}degree polynomial's curve.Let

fbe a differentiable function on the intervalIand letcbe a point on it such that

- ;
f^{(n)}(c) exists and is non-zero.Then,

- if
nis even

- is a point of local maximum
- is a point of local minimum
- if
nis odd is a point of inflection

Oh, that's so obviousâ€”like anyone would need to look *that* up!
