/ /ɛkˈstriːməm/noun (plural extremums or extrema /ɪkˈstriːmə/ /ɛkˈstriːmə/) [usually as modifier] Mathematics
The maximum or minimum value of a function: extremum principles...
- Correlation coefficients showed multiple local extrema with a global maximum, and success in tracking generally relies on the presence of such a maximum at the correct x-y location within each search area.
- Trajectories x that solve Newton's equations are those that are extrema of the action A = [integral operator] L (x, v (t)) dt.
- The first step in solving such equations by the variational method is to show that the extremum is attained.
Origin
Early 20th century: from Latin, neuter of extremus 'utmost' (see extreme).
