  • Relative Minima and Maxima

    • In mathematics, the maximum and minimum of a function (known collectively as extrema) are the largest and smallest value that a function takes at a point either within a given neighborhood (local or relative extremum) or within the function domain in its entirety (global or absolute extremum).
    • Note that we have to speak of local extrema, because any given local extremum as defined here is not necessarily the highest maximum or lowest minimum in the function’s entire domain.

    • So if you draw a graph, make sure you draw no more local extremum points than you should.
