Paraméteres

Paraméteres is a term that can refer to several concepts depending on the context, most commonly found in mathematics, computer science, and engineering. In mathematics, a parameter is a variable that is not dependent on other variables in a function or equation. It is used to define a set of related functions or curves. For instance, in the equation of a circle x² + y² = r², 'r' is a parameter that defines the radius of the circle. Changing the value of 'r' generates a different circle. Similarly, parametric equations express coordinates as functions of one or more independent variables called parameters.

In computer science, a parameter is a variable that is passed to a function or subroutine. It acts as a placeholder for a value that will be supplied when the function is called. This allows for flexible and reusable code, as the same function can operate on different data by passing different parameter values. For example, a function to add two numbers might take two parameters, 'a' and 'b', and return their sum.

In engineering and other scientific fields, parameters are often used to describe the characteristics or properties of a system. These can be physical constants, measurable quantities, or adjustable settings. For example, in thermodynamics, temperature and pressure are parameters that define the state of a substance. In control systems, parameters define the behavior and performance of the system. The term emphasizes that a system's behavior or a mathematical object's definition can be altered by changing these specific values.
