Transcendental Numbers are numbers that cannot be written using an equation.

Like x²+1=0.

If Google has a result for 1.444667861, I am happy. I shall search and then post.

A number that can't be written as an equation eh? Infatuating!

A logarithm is just a misspelled algorithm.

Can you prove it's transcendental?

"In the real world, this would be a problem. But in mathematics, we can just define a place where this problem doesn't exist. So we'll go ahead and do that now..."

Pi is the ratio of a circle's diameter to it's circumference. So if you measured both of these on any given circle, you would find that:

circumference = pi * diameter.

Pi is 3.141592... (the digits go on for ever, and never repeat)

The numbers on the number line can be split onto two groups: those that are *algebraic* and those that are *transcendental*.

Algebraic numbers are a solution to a polynomial equation* where all the coefficients** are whole numbers. So, for example, the number 2 is algebraic, because it is the solution to the equation:

the number [sup]3[/sup]/[sub]2[/sub] is algebraic because it is the solution of:

and the square root of 2 is algebraic, as it is the solution of:

A transcendental number is any number that is not algebraic. As it happens, pi is transcendental.

* a polynomial equation is one like:

or

or

** in the above equations,

, , and are the coefficients of the equation.Bad speling makes me [sic]

Is it known if this number (i.e. e^(1/e)) is transcendental?

Hi zetafunc,

is 1 and is . approaches 2.7182818284....I think it is transcendental. I am not too sure.

It has not been proven to be transcendental, I don't think.
