The ordered pair (a, b) is different from the ordered pair (b, a), unless a = b. In contrast, the unordered pair, denoted {a, b}, always equals the unordered pair {b, a}. Ordered pairs are also called 2-tuples, or sequences (sometimes, lists in a computer science context) of length 2. Ordered pairs of scalars are sometimes called 2-dimensional ...
Given a function: from a set X (the domain) to a set Y (the codomain), the graph of the function is the set [4] = {(, ()):}, which is a subset of the Cartesian product.In the definition of a function in terms of set theory, it is common to identify a function with its graph, although, formally, a function is formed by the triple consisting of its domain, its codomain and its graph.
Cartesian plane with marked points (signed ordered pairs of coordinates). For any point, the abscissa is the first value (x coordinate), and the ordinate is the second value (y coordinate). In mathematics , the abscissa ( / æ b ˈ s ɪ s . ə / ; plural abscissae or abscissas ) and the ordinate are respectively the first and second coordinate ...
A curve point (,) is regular if the first partial derivatives (,) and (,) are not both equal to 0.. The equation of the tangent line at a regular point (,) is (,) + (,) =,so the slope of the tangent line, and hence the slope of the curve at that point, is
Slope illustrated for y = (3/2)x − 1.Click on to enlarge Slope of a line in coordinates system, from f(x) = −12x + 2 to f(x) = 12x + 2. The slope of a line in the plane containing the x and y axes is generally represented by the letter m, [5] and is defined as the change in the y coordinate divided by the corresponding change in the x coordinate, between two distinct points on the line.
An undirected graph with three vertices and three edges. In one restricted but very common sense of the term, [1] [2] a graph is an ordered pair = (,) comprising: , a set of vertices (also called nodes or points);
President Donald Trump on Thursday took executive action to address FAA hires and aviation safety after an Army Black Hawk helicopter collided with a passenger jet in D.C.
In Boolean algebra, a monotonic function is one such that for all a i and b i in {0,1}, if a 1 ≤ b 1, a 2 ≤ b 2, ..., a n ≤ b n (i.e. the Cartesian product {0, 1} n is ordered coordinatewise), then f(a 1, ..., a n) ≤ f(b 1, ..., b n). In other words, a Boolean function is monotonic if, for every combination of inputs, switching one of ...
