In mathematical analysis, the maximum and minimum[a] of a function are, respectively, the greatest and least value taken by the function.

Extrema (maximum and minimum values) are important because they provide a lot of information about a function and aid in answering questions of optimality. Calculus provides a variety of tools to help …

Notice that when a function is defined on a closed interval, an absolute extreme value may occur at the endpoint of that interval of domain, since the endpoint of the interval may yield the largest value of …

Extrema refer to the maximum and minimum values of a function, and they can be categorized into two types: global (or absolute) extrema and local (or relative) extrema.

At this point, we know how to locate absolute extrema for continuous functions over closed intervals. We have also defined local extrema and determined that if a function f has a local extremum at a point c, …

The plural of extremum is extrema and similarly for maximum and minimum. Because a relative extremum is “extreme” locally by looking at points “close to” it, it is also referred to as a local extremum.

Illustrated definition of Extrema: The smallest and largest values (within a given domain): The plural of Minimum is Minima The plural...

Extrema is the general name for maximum and minimum points. This video shows how to identify relative and absolute extrema in the graph of a function.

Problem 13.1: Find all the extrema of the function f(x, y) = 3x ∗ y + x2 ∗ y + x ∗ y2 they are maxima, minima or saddle points.

If we seek to know if and where such extrema occur (both local and absolute), we should be aware of the following two important results. The first gives us a sufficient (but not necessary) condition for a …
