I threw a curve ball to see what he would do, open the door for ideas,
etc, x could be complex, or Pi, or Pi^(x*i)
anyhow I dug this up from wiki -
Transcendental number
From Wikipedia, the free encyclopedia
In mathematics, a transcendental number is a real or complex number that
is not algebraic—that is, it is not a root of a nonzero polynomial
equation with integer (or, equivalently, rational) coefficients. The
best-known transcendental numbers are π and e. Though only a few classes
of transcendental numbers are known (in part because it can be extremely
difficult to show that a given number is transcendental), transcendental
numbers are not rare. Indeed, almost all real and complex numbers are
transcendental, since the algebraic numbers are countable while the sets
of real and complex numbers are both uncountable. All real
transcendental numbers are irrational, since all rational numbers are
algebraic. The converse is not true: not all irrational numbers are
transcendental; e.g., the square root of 2 is irrational but not a
transcendental number, since it is a solution of the polynomial equation
x2 − 2 = 0. Another irrational number that is not transcendental is the
golden ratio, φ {\displaystyle \varphi } \varphi or ϕ {\displaystyle
\phi } \phi , since it is a solution of the polynomial equation x2 − x −
1 = 0.
