Inverse variation, or inverse proportionality, occurs when two variables, and have a relationship such that their product is constant. This relationship is often written with one of the variables isolated on the left-hand side.
The constant, is called the
constant of variation or
the proportionality constant.
The constant of variation may be any real number except
|Examples of Inverse Variation|
|The gas pressure in a sealed container if the container's volume is changed.||depends on the amount of gas there is in the container and the temperature.|
|The time, it takes to travel a given distance at various speeds,||The constant of variation, is the distance.|
Inverse variation is closely related to other types of variation.
