A rational function f(t) with coefficients in a field K is a fraction g(t)/h(t) where f(t), g(t) are in K[t].
a fraction whose numerator and denominator are both polynomials in X
a function formed by taking the ratio of two polynomials
a function that is expressed as the ratio of two polynomials
a function that looks like a fraction
a function which is the ratio of two polynomials
a function whose value is given by a rational expression
Functions constructed using the roots or quotients of polynomials. Example: f(x) = x1/2 g(x) = (2x3 - 4x2 + 2) / (x2 + 1)
A ratio of two polynomial functions, , where .
In mathematics, a rational function is any function whose output can be given by a formula that is the ratio of two polynomials.
