WebTo find a local maximum of a trig function, find the local maxima on the interval [ 0, 2 π) radians. (Note that “maxima” is just the plural of “maximum.”) These will occur at points where the function changes direction from increasing to decreasing. It may sometimes also occur at the endpoints of a given interval. WebA local extremum (or relative extremum) of a function is the point at which a maximum or minimum value of the function in some open interval containing the point is obtained.
