Inverse Variation Calculator

Inverse variation describes a specific type of proportional relationship between two variables, typically denoted as x and y. When two quantities vary inversely, their product remains constant. Mathematically, this relationship is expressed by the formula y = k / x, where k represents the constant of proportionality. Alternatively, you can find the constant by multiplying x and y together (k = x * y). If you know any two values among k, x, and y, this calculator instantly solves for the third missing parameter.

Imagine you are analyzing a physics problem where pressure and volume vary inversely. You are given a constant of proportionality (k) equal to 60, and you need to find the value of y when x equals 4. Using the inverse variation formula y = k / x, you substitute your known values: y = 60 / 4. Performing the division, you find that y equals 15. If x increases to 10, y will decrease to 6, perfectly illustrating the inverse relationship.

Always double-check whether your scenario describes direct variation (where variables increase together) or inverse variation before running your numbers. Keep in mind that the input variable x can never equal zero in an inverse variation equation, as division by zero is undefined and creates a vertical asymptote on a coordinate plane graph.
