Der Fundamentalsatz der Algebra
Die Polynomgleichung \(X^2 + 1 = 0\) besitzt im Zahlbereich der reellen Zahlen keine Losung, wohl aber im Bereich der sogenannten komplexen Zahlen. In diesem Kapitel fuhren wir die komplexen Zahlen…
Analysis of Kneser's Root Finding Algorithm for Polynomials in a Constructive Setting
This Bachelor thesis reproduces the proof of the Kneser Algorithm which is used to find roots of nonconstant polynomials as well as providing an analysis of the algorithm in a constructive setting.…
The Fundamental Theorem of Algebra
The Fundamental Theorem of Algebra (stated below) provides an ideal case study for illustrating the roles of alternative proofs in mathematical practice. Like the Pythagorean Theorem, the Fundamental…

On the Fundamental Theorem of Algebra
One of the simplest proofs that every nontrivial polynomial P has a zero goes as follows. Observe that |P(z)| → ∞ as |z| → ∞, so we may find an R > 0 with |P(z)| > |P(0)| for all |z| ≥ R. Since any…
