Map Numbers Article For Free

Mapping applies to any set: a collection of objects, such as all whole numbers, all the points on a line, or all those inside a circle. For example, ?multiply by two? defines a mapping of the set of all whole numbers onto the set of even numbers.

Approach 1: Use the logarithmic scale to map the range. In this example, first, the log value of the range is calculated and then the scale is calculated using the difference of log values of the target scale to the difference of the start scale.

Standard topographic maps are numbered using a system developed for the International Map of the World. Map areas at million scale are identified by a two letter combination which identifies the hemisphere and a four degree band of latitude and a two digit number which identifies a six degree band of longitude.

Mapping Rule A mapping rule has the following form (x,y) ? (x?7,y+5) and tells you that the x and y coordinates are translated to x?7 and y+5. Translation A translation is an example of a transformation that moves each point of a shape the same distance and in the same direction. Translations are also known as slides.

The simplest kind of numerical mapping is called "linear mapping". That's when a one-to-one correspondence is drawn from every value in a source range X to a value that holds an exactly comparable position in a target range Y.

Last modified +. The range of a mapping (in a mathematical sense) is a set of values that are considered to be valid outputs of the mapping. Definition of mapping range is not important for evaluation of mapping expression. However, it is important for application of mapping outputs.

To map [a,b] onto [c,d], just seek the equation of the line through the points (a,c) and (b,d). A point M(x,y) will lie on this line iff det(AM, AB)=0. i.e., (x-a)(d-c)=(y-c)(b-a).
