    Numbers
In summary, the conversation discusses transcendental numbers and their definition as numbers that cannot be found as solutions to polynomial equations with rational coefficients. The conversation also mentions the constant term in a polynomial equation and clarifies the definition of transcendental numbers.

hi pals
assume that m is a Transcendental number.
as you know we have:
x-m=0 => x=m
x^2-m=0 => x=+ or - sqrt(m)
.
.
.
so there must not be even one Transcendental number.
because all complex and real numbers can be the zero(s) of the equations above.
where is the problem?
thanks

A http://en.wikipedia.org/wiki/Transcendental_number" is, by definition, not the zero of a polynomial with rational coefficients.

isn't 1 rational ?

The constant term of the polynomial, in you case m, is also considered a coefficient (of x^0).

Do you understand the definition of "transcendental number"? A transcendental number is one that cannot be found as a solution to a polynomial equation with integer coefficients. Saying that "x= + or - sqrt{m}" says nothing about whether x satisfies a polynomial equation with integer coefficient.

oh people really excuse me
i understand it now.
sorry for interrupting you
 

1. What are transcendental numbers?

Transcendental numbers are numbers that cannot be expressed as a root of a polynomial equation with rational coefficients. They are numbers that are not algebraic and have infinite non-repeating decimal representations.

2. Who discovered transcendental numbers?

The concept of transcendental numbers was first introduced by the ancient Greek mathematician Pythagoras in the 6th century BC. However, the first proof of the existence of transcendental numbers was given by Joseph Liouville in 1844.

3. Are all irrational numbers transcendental?

No, not all irrational numbers are transcendental. Irrational numbers can be divided into two categories: algebraic and transcendental. While all transcendental numbers are irrational, not all irrational numbers are transcendental. For example, the square root of 2 is irrational but is not a transcendental number.

4. How are transcendental numbers used in mathematics?

Transcendental numbers have important applications in mathematics, particularly in the study of calculus and real analysis. They are used to prove the existence of non-constructible objects, such as the circle, and to solve certain mathematical problems that cannot be solved using algebraic methods.

5. Can transcendental numbers be approximated?

Yes, transcendental numbers can be approximated to any degree of accuracy using rational numbers. However, they cannot be represented exactly as a ratio of two integers. This is because their decimal representations are infinite and non-repeating, making them impossible to express as a fraction.
