Once the variation constant is known, the value of either the dependent variable or the independent variable can be found if the other is known: x = k/y or y = k/x. Putting “Inverse Variation” in Applicable terms: Inverse variation is applicable in many disciplines. For instance a lever is an example of inverse variation.

The two most common types of variation are direct and inverse. Direct Variation: y varies directly. as the nth power of x, or y is proportional to the nth power of x, means that there a number, k, called the . constant of proportionality, such that . Inverse Variation: y varies inversely

Direct and Indirect Variation. Indirect Variation. We gave an example of inverse proportion above, namely speed and time for a particular journey. In this case, if you double the speed, you halve the time. So the product, speed x time = constant. In general, if x and y are inversely proportional, then the product xy will be constant.
