# Can transcendental numbers be rational?

## Can transcendental numbers be rational?

No rational number is transcendental and all real transcendental numbers are irrational. The irrational numbers contain all the real transcendental numbers and a subset of the algebraic numbers, including the quadratic irrationals and other forms of algebraic irrationals.

## Are transcendental numbers irrational?

transcendental number, number that is not algebraic, in the sense that it is not the solution of an algebraic equation with rational-number coefficients. Transcendental numbers are irrational, but not all irrational numbers are transcendental.

Can polynomials functions have irrational coefficients?

The function divide (starting with a lower case d) shouldn’t be used for polynomials with algebraic coefficients. One must use the inert form Divide (starting with an upper case D). However, all irrational algebraic coefficients of the polynomials must then be defined with RootOf’s.

### Are there more algebraic numbers are transcendental numbers?

Transcendental numbers (that is, non-algebraic real numbers) comprise a relatively new number system. Examples of transcendental numbers include e and π. Joseph Liouville first proved the existence of transcendental numbers in 1844. In fact, there exist more transcendental than algebraic numbers.

### What is the difference between algebraic numbers and transcendental numbers?

An algebraic number is any number that is a solution to a polynomial with rational coefficients. All transcendental numbers are irrational, but not all irrational numbers are transcendental. Transcendental numbers are infinite and uncountable because there are far more transcendentals than there are algebraics.

Can polynomials have square root coefficients?

In particular, for an expression to be a polynomial term, it must contain no square roots of variables, no fractional or negative powers on the variables, and no variables in the denominators of any fractions.

## Can polynomials have pi as a coefficient?

Since π and e are transcendental, neither can be the root of a polynomial with rational coefficients. However, it is easy to construct a polynomial transcendental coefficients (with π or e as one of it’s roots), namely (x−π) and (x−e).

## What is the difference between algebraic and transcendental function?

Definition Any function which may be built up using the operations of addition, sub- traction, multiplication, division, and taking roots is called an algebraic function. Example f(x) = ln(15x + 6) is a transcendental function. Example The trigonometric functions are all transcendental functions.

What is the difference between algebraic and transcendental equations?

The equations of the form f(x) = 0 where f(x) is purely a polynomial in x. e.g. x6 – x4 – x3 – 1 = 0 is called an algebraic equation. But, if f(x) involves trigonometrical, arithmetic or exponential terms in it, then it is called transcendental equation.

### Is the square root of an algebraic number algebraic?

A real number is an algebraic number if it is a zero of a polynomial with integer coefficients; and its degree is the least of the degrees of the polynomials with it as a zero. The square root of two is an algebraic number of degree two because it is a zero of x2-2. …

### Can polynomials have roots?

The roots (sometimes called zeroes or solutions) of a polynomial P ( x ) P(x) P(x) are the values of x for which P ( x ) P(x) P(x) is equal to zero. Finding the roots of a polynomial is sometimes called solving the polynomial.
