Constants and Variables are the two types of symbols in algebra. In Mathematics, we usually deal with two types of quantities-Variable quantities (or variables) and Constant quantities (or constants). If the value of a quantity remains unaltered under different situations, it is called a constant...
Variable and constant' are fundamental concepts and they are basis of the branch algebra of mathematics. Research has documented that learners, even a portion of teachers are weak in conceptualizing `variable and constant'. So, the researcher has tried to develop some activities in such a way ...
A fixed value. In Algebra, a constant is a number on its own, or sometimes a letter such as a, b or c to stand for a fixed number. Example: in "x + 5 = 9", 5 and 9 are constants. Example: in "y = ax + b", a and b are constants (and x is a variable)....

It implies duration and effort, such as a sustained pace during a marathon, which might fluctuate slightly but remains deliberately controlled. 11 A constant variable in an experiment is an element that remains fixed throughout, ensuring the experiment's conditions are stable. Whereas, a sustained...
variable. Webster 1828 EditionConstant CONSTANT, Adj. [L.] 1. Fixed; firm; opposed to fluid. To turn two fluid liquors into a constant body. [In this sense, not used.] 2. Fixed; not varied; unchanged; permanent; immutable. The worlds a scene of changes, and to be constant, in na...
Examples of variables are x, y, and z. A coefficient is a number that is directly in front of a variable. It is often a constant if it does not change. Mathematical operations are addition, subtraction, multiplication, and division. An expression is a combination of mathematical operations ...

Step 4:Use algebra to multiply through: 5(3x2) = 15x2 Example Question 2:What is the derivative of -7x-4? Step 1:Separate the constant from the function. -7 x-4 Step 2:Differentiate the functionusing therules of differentiation. The function x-4is an exponent and so is differentiated...
Similarly, a value of the input where a function changes from decreasing to increasing as the input variable increases is called a local minimum. The plural form is “local minima.” Together, local maxima and minima are called local extrema, or local extreme value...
