The variables are, in the field of mathematics, symbols appearing in a function , one formula , one proposition or an algorithm . Their main characteristic is that they have the ability to adopt different values . When the value of a quantity depends exclusively on the value of another quantity, a mathematical function is established . This second magnitude, which determines the value of the first, is called the independent variable . Instead, the quantity whose value depends on the other acts as a dependent variable . It is important that we know that this term is made up of two words that, etymologically speaking, come from Latin: -Variable derives from “variabilis”, which means that something can change its appearance and that it is made up of two different parts: the verb “ variare ”(change appearance) and the suffix“ -able ”, which is used to indicate possibility. -Independent, on the other hand, is the result of the union of three Latin components: the prefix “in-”,...
