pöördvõrdeline

Pöördvõrdeline refers to an inverse proportion or inverse relationship between two quantities. In mathematics, two variables are said to be in inverse proportion if their product remains constant. This means that as one variable increases, the other variable decreases proportionally, such that their product always equals the same value. For example, if the speed of a vehicle increases, the time it takes to travel a fixed distance decreases. The relationship can be expressed as y = k/x, where x and y are the variables and k is a constant of proportionality. This means that y is inversely proportional to x. Conversely, x is also inversely proportional to y. If x1 and y1 are initial values and x2 and y2 are corresponding values, then x1 * y1 = x2 * y2 = k. This concept is fundamental in various scientific and engineering fields, including physics, where concepts like pressure and volume at constant temperature (Boyle's Law) or the relationship between the intensity of light and the square of the distance from the source exemplify inverse proportionality. Understanding pöördvõrdeline relationships helps in predicting how changes in one factor will affect another in a system.
