gollark: Δy/Δx, if you prefer.
gollark: The slope of the line.
gollark: Ah, so if two adjacent things are the same and both extrema it wants the midpoint?
gollark: If they mean approximately the same things as in the calculus I did, then if the gradient was positive/negative on one side and the same sign on the other it would not be a maximum/minimum but just an inflection point. But if the gradient changes sign, then it can be, and this probably requires a different value to on either side. But I don't really get what they're saying either.
gollark: I think to be a valid maximum/minimum it has to be >/< but *not* equal?
