a. Designating an expression involving only the operations of addition, multiplication, raising to a power (squaring, cubing, etc.), and their inverses acting on terms involving constants and variables; spec. (a) designating an equation in which a polynomial in a single variable is equated to zero; (b) designating a function of one variable which is the root of a polynomial in another variable whose coefficients are themselves polynomials with rational coefficients in the first variable. Also: relating to or involving such an expression. Cf. transcendental adj. 4.
