The constant variable is usually the 'X' variable or the variable that stays the same. For example, it may be the 'X' variable or the same number.
The derivate of zero - as well as the derivative of ANY constant (non-variable) number, is zero. (A graph of y = 0 for example will be a horizontal line - the slope is zero.)
There could be a variable in the numerator which is not defined. For example, [tan(x)]/3 has no variable in the denominator but the expression is not defined for x = pi/2, for example (90 deg).
If x causes changes in y, for example 23x3 =y then x is the independent variable and y is the dependent variable.
In the equation 2x 5 11, the number 5 is an example of a non-variable.

A non-example of a control variable is a variable that is not intentionally kept constant or manipulated in an experiment. For example, in a study examining the effects of different teaching methods on student performance, the color of the walls in the classroom would be a non-example of a control variable because it is not being controlled or manipulated by the researcher. Non-examples of control variables can introduce confounding factors that may impact the results of an experiment.
A variable changes. It varies. A non variable does not change. It is constant. For example if I write a mathematical expression such as x + 1, then x is a variable. Its value can be whatever value we choose. However 1 is a non variable. Its value is 1 and never changes from 1. In a scientific experiment a variable would be something that you changed from one test to another. A non variable would be something that remained constant from test to test. As a final example: the speed at which light travels in a vaccum is a constant. It is referred to by the letter c which stands for the universal constant. However, the speed at which your car travels is a variable. It changes.
In mathematics, when the dependent variable is not proportional to the independent variable. The function does not vary directly with the input. Example: y=sin (x).

An variable in science something that can be changed and example is facts and figures .
Linear equations have a variable only to the first degree(something to the power of 1). For example: 2x + 1 = 5 , 4y - 95 = 3y are linear equations. Non-linear equation have a variable that has a second degree or greater. For example: x2 + 3 = 19, 3x3 - 10 = 14 are non-linear equations.
That means finding something that changes, but isn't dependent on something else changing it. I would say that time is a non-example. It keeps changing regardless of how other things are changing. (Now, there is an exception to this in physics, where the passage of time changes in relation to velocity, but we're assuming that we are just talking about time as it is typically for us.) Another example would be something like a quantity purchased. Let's say that candy bars cost $ .75 each. The total cost would be dependent on how many candy bars are purchased, so the total cost would be the dependent variable. The number of candy bars purchased would be the independent variable, since it doesn't depend (within reason) on the total price. Since it is an independent variable, it is not a dependent variable, so it is a non-example of a dependent variable. For example, someone could purchase either 3 or 4 candy bars, and the total price depends on how many are bought, but how many are bought doesn't depend on the total price.

Yes. It is a continuous variable. As used in probability theory, it is an example of a continuous random variable.
