The converse is not true: there are entire transcendental functions f such that f (α) is an algebraic number for any algebraic α. [6] For a given transcendental function the set of algebraic numbers giving algebraic results is called the exceptional set of that function. [7] [8] Formally it is defined by:
Thomae's function: is a function that is continuous at all irrational numbers and discontinuous at all rational numbers. It is also a modification of Dirichlet function and sometimes called Riemann function. Kronecker delta function: is a function of two variables, usually integers, which is 1 if they are equal, and 0 otherwise.

John Herschel, Description of a machine for resolving by inspection certain important forms of transcendental equations, 1832. In applied mathematics, a transcendental equation is an equation over the real (or complex) numbers that is not algebraic, that is, if at least one of its sides describes a transcendental function. [1] Examples include:
A transcendental number is a (possibly complex) number that is not the root of any integer polynomial. Every real transcendental number must also be irrational, since a rational number is the root of an integer polynomial of degree one. [17] The set of transcendental numbers is uncountably infinite.
Mahler proved that the exponential function sends all non-zero algebraic numbers to S numbers: [28] [29] this shows that e is an S number and gives a proof of the transcendence of π. This number π is known not to be a U number. [30] Many other transcendental numbers remain unclassified.
