There are very many uses for Irrational Numbers. A square, whose sides are a rational number, will have a diagonal of irrational length. The diagonals of most rectangles, with rational sides, will be irrational. The circumference and area of a circle (or ellipse) is related to pi, an irrational number. In the same way that pi is central to geometry, another irrational number, e, is fundamental to advanced calculus.

Irrational numbers can not be expressed as fractions whereas rational numbers can be expressed as fractions

Two of the most important numbers in advanced mathematics are pi and e and both are irrational.

The history of irrational numbers is quite simple in that any number that can't be expressed as a fraction is an irrational number as for example the value of pi as used in the square area of a circle.

No. At least, not for his work in the bank. Ans 2. Alan Greenspan said that the numbers that bankers used to cobble together investment products were based on "irrational exuberance". The numbers on which toxic mortgages were based were irrational by any standards.

You will use the numbers pi and e (or applications which use them).

Irrational numbers are used in some scientific jobs. Commonly used irrational numbers are pi, e, and square roots of different numbers. Of course, if an actual numerical result has to be calculated, the irrational number is rounded to some rational (usually decimal) approximation.

An imaginary number i is defined as the square root of -1, so if you have something like the square root of -2, the answer would be i root 2, and that would be considered an irrational non-real number.* * * * *Not quite. The fact that irrational coefficients can be used, in conjunction with i to create complex numbers (or parts of complex numbers) does not alter the fact that all irrational numbers are real numbers.

There are infinitely many irrational numbers between 4 and 6, so the article "the" is used incorrectly. For example, 4.75933201865... is irrational, so is pi + 1 or e + 3.

There is no specific symbol. The symbol for real numbers is R and that for rational numbers is Q so you could use R \ Q.

They are used for counting things. Also, they form the basis for the rest of the number system: the integers, rational numbers, irrational numbers, complex numbers, quaternioins.
