The Algebraic and Transcendental Numbers
A real or complex number z is called algebraic if it is the root of a polynomial equation zn + an − 1zn − 1 + … + a1z + a0 = 0, where the coefficients a0, a1, … an − 1 are all rational; if z cannot be a root of such an equation, it is said to be transcendental. The number
squaring the circle by straight edge and compass alone (see geometric problems of antiquity). The number e has also been found to be transcendental, although it still remains unknown whether e + π is transcendental.
