Excel IF Function. ïConsider the following IF function: =IF(B2>=1000,âA $1000 or betterâ, âLess than a grandâ) ïIf the value of B2 is greater than or equal to 1000, than the. function returns the string âA $1000 or betterâ. ïIf the value of B2 is not greater than or equal to 1000, than the.
Discrete Geometry: Points as Dots. In Discrete Geometry, a point is a dot. Lines are composed of an infinite set of dots in a row. Dots may or may not have size and shape, depending on the version studied. Some common applications of discrete geometry include computer displays and printers. The computer screen I am working on at the moment has 80 columns and 25 rows of characters.
8. (Halmos, p. 100) If X is an infinite set, let (0 (X) be the least ordinal (ï such that there is a bijection from (ï to X; as indicated in the notes, the existence of such an ordinal is a consequence of the Well â Ordering Principle. Explain why (0 (X) is a limit ordinal.. Give examples of sets A, B, C such that each of the three pairwise intersections A (B, A (C, B (B is nonempty but the total intersection A (B (C is empty (this illustrates the importance of recognizing the difference between a disjoint collection of sets and a pairwise disjoint collection of sets).
