COMPLEX NUMBERS - NUMBER THEORY
Complex numbers can be represented as points in the plane, using the cor-respondence x + iy ↔ (x, y). The representation is known as the Argand diagram or complex plane. The real complex numbers lie on the x–axis, 11),). ...

1 Basics of Series and Complex Numbers
people.math.wisc.eduComplex numbers can be de ned as pairs of real numbers (x;y) with special manipulation rules. That’s how complex numbers are de ned in Fortran or C. We can map complex numbers to the plane R2 with the real part as the xaxis and the imaginary part as the y-axis. We refer to that mapping as the complex plane.
Complex Numbers in Polar Form; DeMoivre’s Theorem
