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.
In this section weâre going to be taking a look at the precise, mathematical definition of the three kinds of limits we looked at in this chapter. Weâll be looking at the precise definition of limits at finite points that have finite values, limits that are infinity and limits at infinity. Weâll also give the precise, mathematical definition of continuity. Letâs start this section out with the definition of a limit at a finite point that has a finite value. Definition 1 Let f(x) be a function defined on an interval that contains, except possibly at.
