A variable in an experiment which is held constant in order to assess the relationship between multiple variables [a], is a control variable. [2] [3] A control variable is an element that is not changed throughout an experiment because its unchanging state allows better understanding of the relationship between the other variables being tested.
For Constant, freedom in the sense of the Ancients "consisted of the active and constant participation in the collective power" and consisted in "exercising, collectively, but directly, several parts of the whole sovereignty" and, except in Athens, they thought that this vision of liberty was compatible with "the complete subjection of the individual to the authority of the whole".

In optimal control theory, a control is a variable chosen by the controller or agent to manipulate state variables, similar to an actual control valve. Unlike the state variable, it does not have a predetermined equation of motion . [ 1 ]
As these decisions became theirs to make, anxiety decreased, and emotional regulation improved. And as my kids felt more in control, so did I. What this means for us today. My son, now 7, is thriving.
An example in economics is "If the price of milk falls, ceteris paribus, the quantity of milk demanded will rise." This means that, if other factors, such as deflation, pricing objectives, utility, and marketing methods, do not change, the decrease in the price of milk will lead to an increase in demand for it.
For example, the constant π may be defined as the ratio of the length of a circle's circumference to its diameter. The following list includes a decimal expansion and set containing each number, ordered by year of discovery. The column headings may be clicked to sort the table alphabetically, by decimal value, or by set.
In control theory, a state observer, state estimator, or Luenberger observer is a system that provides an estimate of the internal state of a given real system, from measurements of the input and output of the real system. It is typically computer-implemented, and provides the basis of many practical applications.
