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.
Thus, f is a bounded linear operator and so is continuous. If X is infinite-dimensional, this proof will fail as there is no guarantee that the supremum M exists. If Y is the zero space {0}, the only map between X and Y is the zero map which is trivially continuous. In all other cases, when X is infinite-dimensional and Y is not the zero space, one can find a discontinuous map from X to Y.
