Graph komplexer Polynome im gaußschen Koordinatensystem
The fundamental theorem of algebra states that every polynomial with complex coefficients (of degree at least one) has a complex root. Many proofs for this theorem exist, but - due to it being about complex numbers - a lot of them aren't easy to visualize. This page tries to provide an interactive visualization of a well-known topological proof. We'll work with one specific polynomial (of degree four), but once you've seen the proof, you'll hopefully be convinced that it'll work for all polynomials.
