A point on a curve where the first derivative is equal to zero.
The slope of a function at a particular point. It is the limit of the change in Y over the change in X as the change in X approaches 0.
The highest point in the neighborhood around a point.
The lowest point in the neighborhood around a point.
A point on a curve where the first derivative is equal to zero, but the point is neither a maximum nor a minimum.
The derivative of the first derivative.
The slope of a line is the change in the Y value divided by the change in the X value.
