1. Allg. die vorgesehene Tätigkeit oder Leistung eines Menschen, Apparats oder Bauteils in einem größeren Zusammenhang.
2. In der Mathematik die Abhängigkeit einer Größe von einer anderen. Die Formel der F. ist y = f (x), gelesen: y gleich f von x, wobei x als unabhängige, y als abhängige Variable bezeichnet wird. In einer F. verändert sich y gemäß einer festen Zuordnungsvorschrift analog x. -
3. In der Biologie die Tätigkeit eines Organs im Rahmen des Gesamtorganismus. Ein großer Teil der Krankheiten sind physiolog. F.sstörungen.
4. In der Soziologie der Anteil einer Institution, Gruppe oder eines sonstigen sozialen Elements an der Erhaltung oder Veränderung eines sozialen Systems, z.B. die Rolle der Stadtbevölkerung in der Feudalgesellschaft.
In mathematics, a function f is a non-empty set of ordered pairs (x,f(x)) of which no two can have the same first element. Hence, if f(x) = x2 two ordered pairs are (-2,4) and (2,4). The set of all first elements in a function’s ordered pairs is called the domain; the set of all second elements is the range. In the algebraic expression y = 4x3 + 2, the dependent variable y is a function of the independent variable x, generally written as f(x). Functions are used in all branches of mathematics, physics, and science generally; for example, the formula t = 2pÖ(l/g) shows that for a simple pendulum the time of swing t is a function of its length l and of no other variable quantity (p and g, the acceleration due to gravity, are constants).
(allgemein) Spezielle Wirksamkeit in einem größeren Zusammenhang; Tätigkeit, Amt, Aufgabe.
Differential coefficient; In mathematics, the limit of the gradient of a chord linking two points on a curve as the distance between the points tends to zero; for a function with a single variable, y = f’(x), it is denoted by f’(x), Df(x), or dy/dx, and is equal to the gradient of the curve.
A word that is derived from another word.
The derivative function senses the rate of rise or fall of the system temperature and automatically adjusts the cycle time of the controller to minimize overshoot or undershoot.
ETYM Latin functio, from fungi to perform, execute, akin to Skr. bhuj to enjoy, have the use of: cf. French fonction. Related to Defunct.
1. What something is used for; SYN. purpose, role, use.
2. A relation such that one thing is dependent on another.
3. The actions and activities assigned to or required or expected of a person or group; SYN. office, part, role.
4. A mathematical relation such that each element of one set is associated with at least one element of another set; SYN. mathematical function.
5. A formal or official social gathering or ceremony.
Normal or customary activity.
In the social sciences, the part(s) a person plays in society, either in helping the social system to work or in fulfilling social responsibilities toward others. Role play refers to the way in which children learn adult roles by acting them out in play (mothers and fathers, cops and robbers). Everyone has a number of roles to play in a society: for example, a woman may be an employee, mother, and wife at the same time.
Sociologists distinguish between formal roles, such as those of a doctor or politician, and informal roles, such as those of mother or husband, which are based on personal relationships. Social roles involve mutual expectations: a doctor can fulfill that role only if the patients play their part; a father requires the support of his children. They also distinguish between ascribed roles (those we are born with) and achieved roles (those we attain).
Role conflict arises where two or more of a person's roles are seen as incompatible—for example, a woman who is a daughter to a sick mother and mother to a sick husband or child.
