Real Numbers
Introduction:
The union of the set of rational numbers and irrational numbers forms the set of real numbers.Let us now look at the properties of real numbers.The real numbers include both rational numbers, such as 42 and −23/129, and irrational numbers, such as pi and the square root of two; or, a real number can be given by an infinite decimal representation, such as 2.4871773339..., where the digits continue in some way; or, the real numbers may be thought of as points on an infinitely long number line.
I used to face the problem of finding or identifying the real numbers,but the easiest way to learn about real number is learning to identify them,usually a lot of problems are faced while studying real numbers.The other way to learn about real numbers is to solve more and more problems related to real numbers,basically we can do a lot of exercise related to real numbers.
Every nonnegative real number has a square root in R, and no negative number does. This shows that the order on R is determined by its algebraic structure. Also, every polynomial of odd degree admits at least one real root: these two properties make R the premier example of a Proving this is the first half of one proof of the fundamental theorem of algebra.
Hope you like the above example of Real Numbers.
