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.
A banana is a good non example.

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.
Yes. It is a continuous variable. As used in probability theory, it is an example of a continuous random variable.
is the variable of x an example of abstract representation
This X2/X = X ==========yes X/3 = ?????? ==============No Yes it can. However, dividing by a variable doesn't always work since the variable could evaluate to zero, and you cannot divide by zero. Similar is true if the non-variable is zero.
A variable in algebra is an unknown quantity as for example in the term 5y the variable is y
Any letter of the Greek or Roman alphabet, or any other alphabet can be used to represent a variable. There are also non-alpha symbols, for example for the Dirac constant (or reduced Planck constant).
