The definition of global minimum point also proceeds similarly. If the domain X is a metric space , then f is said to have a local (or relative ) maximum point at the point x ∗ , if there exists some ε > 0 such that f ( x ∗ ) ≥ f ( x ) for all x in X within distance ε of x ∗ .
There is a corresponding greatest-lower-bound property; an ordered set possesses the greatest-lower-bound property if and only if it also possesses the least-upper-bound property; the least-upper-bound of the set of lower bounds of a set is the greatest-lower-bound, and the greatest-lower-bound of the set of upper bounds of a set is the least ...
At points of discontinuity, a Fourier series converges to a value that is the average of its limits on the left and the right, unlike the floor, ceiling and fractional part functions: for y fixed and x a multiple of y the Fourier series given converges to y/2, rather than to x mod y = 0. At points of continuity the series converges to the true ...
Thus the definition of a greatest element is stronger than that of a maximal element. Equivalently, a greatest element of a subset can be defined as an element of that is greater than every other element of . A subset may have at most one greatest element. [proof 1]
under which a sequence of points (x k) converges to point x ∈ X if and only if x k = x for all but finitely many k. Therefore, if the limit set exists it contains the points and only the points which are in all except finitely many of the sets of the sequence. Since convergence in the discrete metric is the strictest form of convergence (i.e ...
The greatest common divisor (GCD) of integers a and b, at least one of which is nonzero, is the greatest positive integer d such that d is a divisor of both a and b; that is, there are integers e and f such that a = de and b = df, and d is the largest such integer.
The geometric mean of / and + / is , meaning that a value of exactly (i.e., =) represents a geometric halfway point within the range of possible values of . Some use a simpler definition where 0.5 ≤ a < 5 {\displaystyle 0.5\leq a<5} . [ 5 ]
Points are at 0.05 s intervals and length of their tails is linearly proportional to their speed. t = time from launch, T = time of flight, R = range and H = highest point of trajectory (indicated with arrows). The range, R, is the greatest distance the object travels along the x-axis in the I sector.
