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.
An introduction to geometry. A point in geometry is a location. It has no size i.e. no width, no length and no depth. A point is shown by a dot. A line is defined as a line of points that extends infinitely in two directions. It has one dimension, length. Points that are on the same line are called collinear points. A line is defined by two points and is written as shown below with an arrowhead. $$\\ \overset{\leftrightarrow}{AB } \\$$ Two lines that meet in a point are called intersecting lines. A part of a line that has defined endpoints is called a line segment. A line segment as the segment between A and B above is written as:
