Resumen
Complex numbers, roots of a polynomial, Argument Principle In the complex plane, consider the image of the contour γ={ │z│= r } under the map p(z) = z^6 + 6z + 10. The argument principle states that the number of roots of p(z) enclosed by γ is equal to the winding number of the origin in the image. As you vary r you can see how this winding number changes Componente Curricular::Educação Superior::Ciências Exatas e da Terra::Matemática
