Open interval notation: (a,b); Closed interval notation: [a,b]; and Half-open interval notation: (a,b] or [a,b). How to use this inequality to interval notation calculator? Here we explain how our inequality to interval notation calculator works: Start by choosing the calculator mode, ...
Activity 1:On a paper mark two points Y and Z and join them to form a straight line. Mark another point X outside the line lying on the same plane of the paper. Join XY as shown. Now mark another point X’ on the line segment XY, join X’Z. Similarly, mark X’’ and join ...
The task is to express the exact answer in interval notation, restricting your attention to -2π ≤ x ≤ 2π. Homework Equations The given inequality: cos(x) ≤ 5/3 The Attempt at a Solution I have only one doubt here, and I don't see my mistake. I see that if cos(x)... ...
, the set of 2-element subsets of V, and we view the graph G as an ordered pair G = (V,E). (The notation is set up so that .) Now one of the great features of graphs, as opposed to some other abstract maths concepts, is that they are easy to draw: the abstract vertices be...
