Complex Numbers in Algebra

  • John Stillwell
Part of the Undergraduate Texts in Mathematics book series (UTM)


Over the last few chapters it has often been claimed that certain mysteries— de Moivre’s formula for sin (Section 6.6), factorization of polynomials (Section 6.7), classification of cubic curves (Section 8.4), branch points (Section 10.5), genus (Section 11.3), and behavior of elliptic functions (Sections 11.6 and 12.6)—are clarified by the introduction of complex numbers.
